Contact Lens Clinic
Since Dr Rajat is a cornea specialist, and the contact lens is worn on the cornea- our centre has the most updated contact lens clinic in this region. The department is headed by Dr Rajat himself and he is assisted in this work by his optometrists Neelam and Aastha. We have a special team of visiting contact lens experts who deal with all latest nuances in this field.
With the advent of newer contact lenses, there has been a widespread use of contact lenses in various conditions. Some of the most common are:
- Refractive error – to substitute glasses
- Prosthetic coloured lenses
- Semi-soft lenses – for keratoconus
- Rigid lenses for corneal ectatic disorders
- Scleral/Mini scleral lenses for corneal abnormalities and very severe dry eye.
Do’s and Don’t’s
- Always wash your hands with soap and running continuous water before application or removal of the contact lens.
- For beginners, apply lenses while leaning over a table or a flat surface with a clean cloth. This is so that the lens if it falls is easy to spot and does not get infected.
- If you drop the lens, touch and pick it with a wet forefinger using a solution. Clean and rinse with the contact lens solution before inserting.
- Only use the recommended contact lens solution for storage. Replace the solution every night even if you didn’t use the lens on the day.
- While on travel or work, always keep a pair of spectacles handy.
- Never use lenses while swimming or while sleeping.
- Consult your doctor immediately if you have an unexplained redness, persistent pain, decreasein vision, excessive tearing, light sensitivity or eye discharge.
Mini Scleral Lens is a treatment that restores visual function, supports healing, reduces symptoms and improves quality of life for patients suffering with complex corneal disease. It uses custom designed and fabricated prosthetic devices to replace or support impaired ocular surface system functions.
During treatment doctors customize prosthetic devices for each patient’s condition and unique eye shape. Prosthetic devices are manufactured on site at our state of the art Manufacturing Lab
The goals of the treatment are to:
- Reduce symptoms and support healing by restoring a healthy ocular surface environment
- Improve blurry vision by masking surface corneal irregularities and transmitting a sharp image to the back of the eye
- Prevent damage by protecting the cornea against the environment and eyelids
The prosthetic devices similar to an oversized hard contact lens and resemble a margarita glass without the stem in shape. These lenses fit under the eyelids, vaulting the damaged cornea and resting on the sclera (the relatively insensitive white tissue of the eye). Worn during waking hours, patients are trained in daily application, removal and cleaning as part of the treatment process.
The lenses are made out of a highly gas-permeable hard plastic that allows oxygen to reach the cornea. They are designed to create a space between the prosthetic device and the eye that is filled with sterile saline. The liquid remains in the reservoir, providing constant lubrication by bathing the eye in a pool of artificial tears. Prosthetic devices are customized by specially-trained cornea surgeons and made on-site at the Manufacturing Lab.
Mini scleral lens creates:
- A new transparent, smooth optical surface over the irregular, damaged, or diseased cornea
- An expanded artificial tear reservoir that provides constant lubrication while maintaining necessary oxygen supply
