iDesign Custom Lasik

iDesign Custom Lasik

If you thought that just laser eye surgery was impressive, then be prepared to be astounded by the arrival of iDesign custom Lasik. iDesign is the most advanced wavefront-guided laser treatment available. The system creates a uniquely accurate measurement of the entire optical system that can be relied upon completely without any guesswork. This is then used to create a highly detailed topography or map of your eye, making it easier for your surgeon to pinpoint the areas that need addressing with pinpoint precision. 
 

How accurate is iDesign?

iDesign is extremely accurate due to its diagnostic equipment that is able to determine 1,257 different micro eye prescriptions. Each one of these will measure the eye prescription to 0.01 of a dioptre strength – 25 times more than what a regular prescription for glasses or contact lens prescription is measured to. 
 

Who is iDesign suitable for?

While iDesign Custom Lasik can benefit almost any patient with refractive problems, it is particularly beneficial for people who have unusual corneas or have had eye surgery in the past.
 

Is it painful?

Laser eye surgery is generally considered a pain-free procedure by the majority of patients. Anesthetic eye-drops are used to numb the outer area of the eye during the course of the surgery. Once these have worn off, some patients do experience some mild discomfort during the days following the procedure, but over the counter pain relief is usually sufficient to relieve this.

Am I a candidate for LASIK?

Am I a candidate for LASIK?

If you already rely on wearing glasses or contact lenses to be able to see clearly, you may be frustrated with the effect that they have on your life. Regular vision tests, finding glasses to suit your face shape, having to remember to take eyeglasses with you wherever you go, prescription sunglasses, fiddly contact lenses… the list of inconveniences associated with conventional ocular solutions is extensive. 

LASIK is a modern, minimally-invasive procedure that can substantially reduce or eliminate your need to use eyeglasses or contact lenses, allowing you to enjoy life without limitations or inconvenience. The popularity and success of LASIK laser eye surgery have helped to make it the number one elective surgery across the globe.
 

Candidacy for LASIK

LASIK has an extremely high success rate. According to the American Society of Cataract and Refractive Surgery, 96% of patients achieve 20/20 vision or better. However, it’s high success rate doesn’t make LASIK automatically the right solution for everyone.

Candidacy for LASIK is assessed by our doctors on a case by case basis so that you be certain that whatever treatment is recommended for you, it will give you the very best opportunity to improve your vision. During your consultation, our doctors will perform a thorough examination of your eyes and vision, ask you about your general health and talk you through both the procedure and aftercare.

The general guidelines for LASIK candidacy state that patients must:

  • be at least 18 years of age

  • have had stable vision with no prescription changes for a minimum of 12 months

  • have a current prescription for eyeglasses or contact lenses that falls between specified parameters (Our doctors will be aware of what these parameters are)

  • have no significant medical or eye-related problems such as glaucoma, macular degeneration or diabetic retinopathy

  • have no history of corneal disease

  • not be pregnant or nursing at the time of the procedure

LASIK Co-Management

LASIK Co-Management

LASIK co-management is an integral part of vision correction surgery that often goes unnoticed. It involves a partnership between your primary eye care professional and your LASIK surgeon. This cooperative approach ensures that you're provided with the best possible care before, during, and after your procedure.

LASIK co-management is the collaborative effort of your eye care team to ensure your vision correction procedure is safe and successful. It's a team approach where everyone plays a significant role in your eye health journey.
 

The Evaluation Process

The evaluation process in LASIK co-management is thorough and meticulous. It begins with a comprehensive eye examination by your primary care optometrist. This examination is meant to ascertain your eye health status and determine if you're an appropriate candidate for the LASIK procedure.

The evaluation process underscores the collaborative nature of LASIK co-management. Every step is carefully coordinated to ensure your eye health is prioritized and that you're receiving the best possible care.
 

The Importance of Consultation in LASIK Co-management

Consultation is a crucial aspect of LASIK co-management. It allows for patient education, addressing concerns and questions, and establishing a clear understanding of the expected outcomes.

During the consultation phase, your optometrist will explain the results of your eye examination and how it relates to your suitability for LASIK surgery. They will also discuss the risks and benefits of the procedure, giving you a balanced perspective to make an informed decision.

The consultation with your LASIK surgeon will delve into the specifics of the operation, including the technology used, the surgical process, and the anticipated recovery timeline. Having the opportunity to consult with both your optometrist and your surgeon ensures that all your concerns are addressed, allowing you to proceed with confidence.
 

The Role of Communication

Effective communication is the backbone of successful LASIK co-management. It facilitates a seamless transition from your optometrist to your surgeon, creating a cohesive care plan that's centered around your specific needs.

This communication is not just between healthcare providers but also involves the patient. Regular updates on your progress, detailed explanations about each stage of the process, and addressing any concerns or questions you may have are all essential parts of the communication process.

LASIK Procedure

LASIK Procedure

If you are one of the thousands of people considering LASIK laser eye surgery, then you will probably be gathering as much information as possible about the treatment. By this point, you are probably aware of the benefits that LASIK offers, such as a reduced or eliminated need for glasses or contact lenses and greater convenience in your day-to-day life. However, for many patients, despite the advantages of LASIK, the thought of surgery on their eyes is still a cause of anxiety and fear. One of the best ways to alleviate this concern is to find out more about what the procedure entails.

Your consultation

Before you can be approved for any form of laser vision correction, including LASIK, you will need to attend a consultation appointment with your surgeon. During the consultation, your surgeon will perform an examination of your eyes and use your medical and ocular history to determine if you are a good candidate for the procedure. He will also speak to you about the expected outcome from your surgery, making you aware that while LASIK will dramatically improve your eyesight, there is no guarantee that you will not need to wear glasses in some situations, such as while driving in the dark. 

How LASIK Works

LASIK uses a cool, ultraviolet beam of light to reshape the patient’s cornea. Doing so will more accurately focus the light that enters the eye on to the retina, thus improving the patient’s vision. The way in which the cornea needs to be reshaped will depend on the visual needs of the patient. For example, a patient who is far-sighted will need their cornea reshaping to be steeper to experience better eyesight. Alternatively, a patient who is near-sighted will require their cornea to be flattened in order to improve their vision. LASIK can also smooth an irregular cornea into a more standard shape, meaning that the procedure can also be used to correct astigmatism.

The LASIK procedure

The LASIK procedure is very fast and straightforward. Although you will probably be in the surgical suite for around half an hour, the actual process only takes a couple of minutes per eye. The rest of the time will be spent preparing and ensuring that you are comfortable. Anesthetic eye drops are given to patients before their procedure so that the entire process is pain-free. If you are particularly anxious, it may also be possible for you to be slightly sedated – this should be discussed with your doctor at your consultation appointment.

Once you are in position, we will use a femtosecond laser to cut a thin, circular flap into the outer cornea. This can then be pulled back to reveal the underlying corneal tissue, known as the stroma so that it can be reshaped using the laser. The exact path that the laser needs to take, known as the topography, will have been pre-programmed ahead of the procedure and can be followed with complete precision and accuracy.

Once the reshaping is complete, the flap is replaced back over the eye, and the surgery is complete. There is no need for sutures or bandages as the cornea will start to heal immediately and without any medical intervention.

Cosmetic Services

Cosmetic Services

We all want to look our best and in the last decade, we have seen a significant increase in the number of people seeking cosmetic services in order to enhance their appearance. With our eyes being our most distinguishing feature, we want to make the most of them. Thankfully there is now a range of cosmetic services that can help to rejuvenate our eyes and the area around them to keep them fresh, young and wrinkle-free. 

Let’s take a look at some of the services on offer.

Pigment removal

The brown pigment spots that appear on the face are often referred to as age spots and are a result of sun exposure. With age, the repeated exposure to UV rays causes melanin, a compound that is responsible for pigmentation and protecting the skin begins to clump together to form an area of hyperpigmentation. Whilst they aren’t any cause for concern, many people feel that they look unsightly. Luckily, there are a number of different treatments that you can get to remove them including topical creams, laser therapy, and chemical peels.

If you are suffering from darker pigmentation then we strongly recommend that you make an appointment with a qualified dermatologist who will recommend the best course of treatment for you, based on your specific needs.

Optos

Optos

As technology continues to advance, so does the field of the optometric industry. The development of innovative tools and techniques has allowed for more accurate and comprehensive examinations. One such technology is Optos, a revolutionary system that utilizes ultra-widefield retinal imaging technology to provide optometrists with a detailed view of the entire retina.
 

How Does Optos Work?

Optos technology is based on the principle of ultra-widefield retinal imaging, which allows for a wider and more detailed view of the retina compared to traditional imaging techniques. The Optos system consists of a specialized camera that captures high-resolution images of the retina using scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT) technologies. SLO provides a wide-field view of the retina, while OCT allows for cross-sectional imaging, providing valuable insights into the various layers of the retina.

The Optos camera is designed to capture images through a process called optomap, which captures up to 200 degrees of the retina in a single image. This wide-field view provides optometrists with a comprehensive picture of the retina, enabling them to detect abnormalities that may not be visible with traditional imaging techniques. The optomap image can be instantly viewed and analyzed by your eye doctor, allowing for a more efficient and accurate diagnosis.
 

Common Eye Conditions Detected by Optos

Optos technology has the capability to detect a wide range of eye conditions, including but not limited to, diabetic retinopathy, macular degeneration, glaucoma, and retinal tears or detachments. Diabetic retinopathy is a condition that affects individuals with diabetes, causing damage to the blood vessels in the retina. Optos can capture detailed images of the retina, enabling optometrists to detect any signs of diabetic retinopathy and initiate appropriate treatment.

Macular degeneration is another common eye condition that can be detected using Optos. This condition affects the macula, the central part of the retina responsible for sharp, central vision. Optos allows for a comprehensive view of the macula, identifying any changes or abnormalities that may indicate the presence of macular degeneration.

Glaucoma, a condition characterized by damage to the optic nerve, can also be detected using Optos. The wide-field view provided by Optos allows for a thorough examination of the optic nerve and the surrounding structures, facilitating early detection and intervention.

Finally, Optos technology is particularly effective in detecting retinal tears or detachments. These conditions can lead to sudden vision loss and require immediate medical attention. Optos allows for a comprehensive view of the retina, identifying any signs of retinal tears or detachments and initiate prompt treatment.

Visual Field

Visual Field

Visual field testing is an important part of most standard comprehensive eye exams. Also sometimes known as perimetry testing, Visual field testing is a method to measure the entire scope of vision of an individual, including their peripheral/side vision.
 

The importance of visual field testing

Visual field testing is one of the most effective diagnostic treatments in the detection of glaucoma. This is because when patients are affected by glaucoma, it is usually the peripheral vision that is affected by their condition first. However, it can also be used to detect central or peripheral retinal diseases, eyelid conditions such as drooping, optic nerve damage and conditions that affect the visual pathways from the optic nerve to the area of the brain where this information is processed into vision.

Visual field testing is also an important part of monitoring for people who are considered to be at risk for vision loss from disease and other problems, including those who have been diagnosed with the following:

  • Multiple sclerosis

  • Hyperthyroidism

  • Pituitary gland disorders

  • Central nervous system problems (such as a tumor that may be pressing on the brain)

  • Stroke

  • Diabetes

  • High blood pressure

Optical Coherence Tomography

Optical Coherence Tomography

Optical Coherence Tomography is a non-invasive imaging test that may be performed as a standard part of your regular, comprehensive exams, or you may be able to request this test as an addition to your usual exam.

Optical Coherence Tomography uses light waves to take cross-section images of your retina, which is the area of light-sensitive cells at the back of your eye that is responsible for receiving light and transmitting it into messages that are sent up to the brain. The technology behind OCT enables your eye doctor to see each of the different layers that make up the retina. By being able to see these and measure them, they can obtain a much clearer picture of the overall health and condition of your eyes.
 

Why are Optical Coherence Tomography scans important?

When you choose to have an OCT scan at fairly regular intervals, such as during your normal comprehensive eye exams, your eye doctor can compare newer results to previous ones. This helps them to build up a picture of the health of your eyes, and spot any changes which may be concerning, early, before they cause symptoms or have a permanent effect on your vision. 

Anyone can have an OCT scan, but they are particularly recommended for patients over the age of 25 who are concerned about the health of their eyes, or who are at risk of or already have diabetes, glaucoma or a family history of eye disease. This is because they can be used to spot the early signs of a range of eye diseases, including glaucoma, diabetic retinopathy, macular degeneration, disorders of the optic nerve and more – even before you realize that you are affected.

Ocular Aesthetics

Ocular Aesthetics

Ocular aesthetics, which focuses on improving the appearance of the eyes and the surrounding area, has gained significant popularity in recent years. Ocular aesthetics aims to rejuvenate the eyes, making them appear more youthful, vibrant, and refreshed. This can be achieved through advanced technology treatments that are designed to address specific concerns and enhance the overall appearance of the eyes.
 

Common Concerns in Ocular Aesthetics

There are several common concerns that individuals seek to address through ocular aesthetics. These concerns may be a result of natural aging, genetics, or lifestyle factors. One of the most common concerns is the appearance of wrinkles and fine lines around the eyes, commonly known as crow's feet. These lines can make you look older and tired.

Another common concern is the presence of dark circles and puffiness under the eyes. This can give the impression of fatigue and detract from the overall attractiveness of the eyes.
 

IPL and How it Works

Intense Pulsed Light (IPL) has emerged as a popular and effective treatment option in ocular aesthetics. IPL works by emitting high-intensity light pulses that target specific chromophores in the skin, such as melanin and blood vessels. This targeted approach allows for precise treatment of various concerns around the eyes.

IPL treatments can effectively address pigmentation irregularities, such as age spots and sun damage, which often contribute to an aged appearance. By targeting these concerns, IPL can help restore a more even skin tone and improve the overall aesthetics of the eyes.

IPL treatments are non-invasive and typically require minimal downtime. The number of sessions needed may vary depending on the specific concerns being addressed. By consulting your optometrist, you can determine the best treatment plan to achieve your desired ocular aesthetics.
 

Radiofrequency (RF) for Ocular Aesthetics

Radiofrequency (RF) treatments have gained significant popularity in ocular aesthetics due to their effectiveness in addressing various concerns around the eyes. RF works by delivering controlled radiofrequency waves into the deeper layers of the skin, stimulating collagen production and tightening the tissues.

One of the primary concerns that RF treatments can address is drooping eyelids. As we age, the skin around the eyes can lose elasticity, causing the eyelids to sag. RF treatments can effectively tighten the skin, resulting in a more youthful and lifted appearance. This can help restore the natural contour and symmetry of the eyes, enhancing their overall aesthetics.

RF treatments can also target under-eye bags, which can make the eyes appear tired and aged. By stimulating collagen production, RF can improve the overall tone and texture of the skin, reducing the appearance of under-eye bags and giving the eyes a more refreshed and vibrant look.
 

Exploring Low-Level Light Therapy (LLLT)

Low-Level Light Therapy (LLLT) has gained recognition in ocular aesthetics for its ability to promote cellular activity and stimulate collagen production. LLLT utilizes specific wavelengths of light that penetrate the skin, triggering a series of biological responses that can improve the health and appearance of the eyes.

LLLT treatments can effectively address concerns such as fine lines, wrinkles, and dark circles around the eyes. By stimulating collagen production, LLLT can help reduce the appearance of these concerns, resulting in a more youthful and vibrant look.

In addition to its anti-aging benefits, LLLT can also improve the overall health of the eyes. By promoting cellular activity, LLLT can enhance circulation, reduce inflammation, and support the natural healing process. This can be particularly beneficial for individuals with conditions such as dry eyes or eye fatigue.

Amniotic Membranes

Amniotic Membranes

Dry eye isn’t always just “not enough tears.” Often, the surface of the eye is irritated and inflamed, so tears don’t stay smooth or stable. For some people with more severe symptoms, amniotic membrane therapy can help by acting like a protective bandage that calms the surface and supports healing. 


What Are Amniotic Membranes?

Amniotic membranes are derived from the innermost layer of the placenta and are carefully processed for medical use. Amniotic membranes are used to support regeneration of the corneal surface.

They contain growth factors and biologically active components that:

  • Reduce inflammation 

  • Promote tissue healing

  • Minimize scarring

  • Protect the surface of the eye


Because they are immune-privileged and thoroughly screened, they are considered safe and well.
 

How Do Amniotic Membranes Help Dry Eye?

In moderate to severe dry eye disease, chronic inflammation can damage the corneal surface. This damage can lead to persistent discomfort, fluctuating vision, and delayed healing.

Amniotic membranes work by acting as a biological bandage. Once placed on the eye, they:

  • Create a protective barrier over the cornea

  • Reduce surface inflammation

  • Encourage regeneration of healthy cells

  • Restore smoother corneal tissue


By addressing the underlying inflammation and surface damage, amniotic membranes do more than simply mask symptoms - they promote healing at the source.
