The most widely performed type of refractive surgery is LASIK (laser-assisted in situ keratomileusis), where a laser is used to reshape by using the principle of ablation of cornea using Excimer Laser. Like other types of refractive surgery, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision. In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes. The results improved vision without eyeglasses or contact lenses can usually be seen in as little as 24 hours.
In bladeless LASIK also called blade-free LASIK, all-laser LASIK, or femto LASIK. An-noor eye hospital uses two types of lasers for the vision correction procedure.
– An ultra-fast femtosecond laser is used to create a thin flap in the cornea (the clear front surface of the eye. Then, an excimer laser is used to reshape the underlying corneal tissue to correct your vision. The flap is then returned to its original position.
– The femtosecond laser eliminates the need for a bladed surgical tool (called a microkeratome) to create the corneal flap. No surgical blade of any kind is needed in this laser LASIK.
— Epi-LASIK involves cutting a very thin flap of tissue from the epithelium that covers the front of the eye’s surface (also called the cornea). Epi-LASIK differs from conventional LASIK eye surgery mostly because of the type of flap created. The flap cut is so thin that it does not penetrate the actual cornea, whereas LASIK actually penetrates into the cornea.
— With Epi-LASIK the surgeon uses epithelial separator to separate the sheet from the eye. After the epithelial separator has created this ultra thin flap the flap is lifted and carefully folded back. The next step involves using an excimer laser as is used in conventional LASIK. The laser treatment then reshapes the surface of the eye. The epithelial flap is gently repositioned back on the eye and a contact lens bandage may be required after the surgery to assist with the healing process.
What is an ICL?
The ICL (Implantable Collamer Contact Lens) is a state-of-art refractive error solution that is ideal for anyone who has the need or desire for removal of power with high quality of vision correction. ICL or Implantable Contact Lens, as the name suggests, is a kind of lens which is implanted into the eye and does not require frequent removal like a normal contact lens. This phakic intraocular lens has numerous advantages including its correction of the widest range of myopia (near sightedness), hyperopia (far sightedness) and astigmatism (cylindrical power).
Advantages of ICL?
- Preserves accommodation
- No corneal tissue removed
- Retains corneal asphericity
- Possibly retains contrast sensitivity.
- No blood! No pain! No hospitalisation!
- Almost all levels of power can be treated.
- Excellent quality of vision.
- Easily removed or replaced ( 5 – 10 minutes)
- Cosmetically good as it’s INVISIBLE!!
- Fast recovery
Suitable ICL candidate
- Candidates for the ICL are between 21 and 45 years of age, suffer from myopia (nearsightedness),hyperopia (farsightedness) and astigmatism (cylindrical power) and want to experience superior vision correction.
- The ideal ICL candidate has not undergone any ophthalmic surgery and does not have a history of eye disease such as iritis, glaucoma, or diabetic retinopathy.
- Women who are pregnant or nursing should wait to have the ICL implanted. Lastly, those without a large enough anterior chamber depth or endothelial cell density may not be a good ICL candidate.
Procedure of ICL
The implantation procedure for the ICL (Implantable Contact Lens) is refractive eye surgery that involves a procedure similar to the intraocular lens (IOL) implantation performed during cataract surgery. The main difference is that, unlike cataract surgery, the ICL eye surgery does not require the removal of the eye’s natural lens. The ICL procedure is a relatively short outpatient procedure that involves several important steps. The surgical procedure to implant the ICL is simple and nearly painless.
As a ICL candidate, your doctor will prepare your eyes one to two weeks prior to surgery by using laser to create a small opening between the lens and the front chamber of your eye (iridotomy). This allows fluid to pass between the two areas, there by avoiding the buildup of intraocular pressure following the surgery. However, some surgeons choose to do this step on the same day of the surgery.
Actual procedure time is not more than 20-25 minutes. You can expect to experience very little discomfort during the ICL implantation. You will undergo treatment while under a light topical or local anesthetics. Following surgery, you may use prescription eye drops or oral medication.
