REFRACTIVE EYE SURGERY


What is Refractive Eye Surgery?


Refractive eye surgery is performed to correct the refractive error such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Refractive eye surgery is used to correct or improve your vision by correcting or adjusting your eye-focusing ability by reshaping the cornea or removing the top layer of the cornea. This surgery decreases your dependency on the prescribed eyeglasses or contact lenses. It helps you improve your vision. Refractive surgery has various types and each type has its own characteristics. In the further article, you will know about the types of refractive surgery, its benefits and limitations.

Types of refractive surgery


There are many kinds of refractive surgery and each type has its own functions:-

1. LASIK eye surgery:-


LASIK eye surgery is performed to remove your glasses. It provides better vision by correcting the refractive errors occurring in your eyes. In this surgery, a laser is used to change the shape of your cornea. This surgery is very common and popular. It is also known as glass removal surgery.


2.SMILE eye surgery:-


The full form of SMILE is Small Incision Lenticule Extraction. SMILE surgery can be the alternative to LASIK surgery. This surgery is performed to improve vision by correcting refractive errors. Refraction is performed by the cornea and retina. SMILE surgery changes the curvature of your cornea and enables you to see clearly.


3. Corneal Inlays: -


A corneal inlay is a tiny device smaller than the width of an eraser tip. This is a 10 or 15 minutes surgery in which a laser is used to cut a small pocket or flap in the middle of the cornea. And then, inlays are inserted in the small pocket or flap in the eye’s cornea. This surgery also provides you a sharp vision.


4. Radial Keratotomy and Astigmatic Keratotomy:-


In this surgery, the shape of the cornea is changed by making a deep incision in cornea using a diamond or a stainless steel blade or femtosecond laser and make your vision improved.


5. Phakic intraocular Lenses: -


Phakic intraocular lenses are lens implants used to treat myopia with or without astigmatism in patients and it is an alternative to laser vision correction. Phakic is superior to laser vision correction as they do not alter corneal curvature. Phakic intraocular lenses are directly inserted anterior or posterior to the iris through an incision in the eye.


6. Clear Lensectomy: -


Clear lensectomy is recommended for the patients who have hyperopia and are already presbyopic. This procedure is identical to cataract surgery except the patient’s lens is clear and not cataractous.


7. Intracorneal Ring Segments: -


Intracorneal segments are thin arc-shaped segments of biocompatible plastic that are placed in pairs through a small redial corneal incision into the peripheral corneal stroma at two-third depths. It maintains a central, clear, optical zone as the two segments are placed in the corneal periphery. Intracorneal ring segments can be removed if you want.

Frequently Asked Questions

Find answers to common questions about LASIK, SMILE and refractive eye surgery in Delhi NCR.

What is refractive eye surgery in Delhi?

Refractive eye surgery is a group of procedures used to reduce dependence on glasses or contact lenses by correcting refractive errors such as myopia, hyperopia and astigmatism. At Bharti Eye Foundation in New Delhi, refractive surgery options may include LASIK, SMILE and other vision-correction procedures depending on the patient's eye condition and suitability.

What is the best LASIK eye surgery in Delhi?

The best LASIK procedure depends on your eye power, corneal thickness, corneal shape, tear-film health, age and overall eye condition. A detailed pre-operative eye examination is necessary before selecting LASIK or another vision-correction procedure. Patients in Delhi NCR can consult a refractive eye specialist at Bharti Eye Foundation for an individual assessment.

Who is eligible for LASIK eye surgery in Delhi NCR?

A suitable LASIK candidate generally needs a stable spectacle prescription, healthy corneas and good overall eye health. Age, corneal thickness, corneal mapping, dry-eye status and the type and amount of refractive error are also considered. A comprehensive examination at a refractive surgery centre in Delhi is required to determine individual eligibility.

Can LASIK remove glasses permanently?

LASIK can significantly reduce dependence on glasses or contact lenses, and some patients may achieve clear vision without them. However, LASIK cannot guarantee that a person will never need glasses again. Some patients may require glasses for specific activities or later in life because of natural age-related changes in near vision.

Is SMILE eye surgery better than LASIK?

SMILE is an alternative laser vision-correction procedure to LASIK, but neither procedure is universally better for every patient. The appropriate option depends on factors such as refractive error, corneal characteristics, eye health and lifestyle. An eye specialist in Delhi NCR can evaluate your eyes and recommend the procedure most appropriate for your individual needs.

Is laser eye surgery safe in Delhi?

Laser eye surgery can be safe and effective when patients are appropriately selected and the procedure is performed following proper pre-operative evaluation and surgical protocols. Like every surgical procedure, it has potential risks and side effects. A complete eye examination before refractive surgery is important for identifying conditions that may affect safety or outcomes.

What tests are done before LASIK surgery?

Before LASIK, an ophthalmologist evaluates your vision and refractive prescription and examines the health of your eyes. Corneal mapping or topography/tomography, corneal thickness measurement and assessment of the ocular surface and tear film are important parts of refractive surgery evaluation. These tests help determine whether LASIK or another procedure is appropriate.

How long does it take to recover from LASIK eye surgery?

LASIK generally has a relatively short recovery period, but the exact recovery experience varies between patients. Vision may improve quickly after surgery, while visual quality and eye comfort can continue to stabilize over time. Your refractive surgeon in Delhi will provide specific instructions regarding eye drops, activities, follow-up visits and returning to normal activities.

What are the side effects of refractive eye surgery?

Possible side effects of refractive surgery include temporary dry eyes, glare, halos, light sensitivity and fluctuations in vision. Other complications can occur less commonly. The risks depend on the procedure and individual patient factors, which is why proper screening and discussion with a qualified eye surgeon are important before surgery.

Can refractive surgery correct high eye power?

Refractive surgery can correct many cases of myopia, hyperopia and astigmatism, but not every level of eye power is suitable for every laser procedure. Patients with higher prescriptions may require an alternative approach depending on corneal thickness, corneal shape and other factors. A refractive eye specialist in Delhi NCR can assess the available options.

What is glass removal surgery in Delhi?

“Glass removal surgery” is a common term used for refractive or laser vision-correction procedures such as LASIK and SMILE. These procedures are designed to reduce dependence on spectacles or contact lenses by correcting refractive errors. Bharti Eye Foundation in New Delhi provides evaluation for refractive surgery to determine which treatment may be suitable for each patient.
