LASIK Eye Surgery

LASIK Eye Surgery in India - Vision Problems LASIK Can Correct

LASIK is a laser eye surgery that reshapes the cornea to correct vision. This short explains the common refractive errors that LASIK can treat.

How LASIK corrects vision

LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a popular procedure for vision correction.

• Reshaping the cornea. The procedure uses a precise laser to change the shape of your cornea, the clear front part of the eye. This helps light to focus correctly on the retina.
• Correcting refractive errors. The surgery aims to correct common focusing problems. This can reduce or even eliminate your need for glasses or contact lenses.
• A quick procedure. The surgery itself is usually very quick, often taking less than 30 minutes for both eyes. Numbing eye drops are used so you should not feel pain.

Which conditions can be treated

LASIK is most effective for certain types of refractive errors within a specific range. Your specialist will determine if your prescription is suitable.

• Myopia (short-sightedness). This is when you can see nearby objects clearly, but distant objects are blurry. LASIK can flatten the cornea to correct this.
• Hyperopia (long-sightedness). This is when you can see distant objects clearly, but nearby objects are blurry. LASIK can make the cornea steeper to correct this.
• Astigmatism. This is caused by an irregularly shaped cornea, leading to blurred vision at all distances. LASIK can smooth the cornea into a more regular shape.

Determining your suitability

• Stable prescription. Your glasses or contact lens prescription should be stable for at least one to two years before the surgery.
• Good eye health. You should not have any significant eye conditions such as severe dry eye, advanced glaucoma, or cataracts.
• Corneal thickness. Your cornea must be thick enough for the surgeon to safely create the corneal flap and perform the reshaping. This is measured with special scans.
• General health. Certain medical conditions or medications may affect your suitability or the healing process. This will be discussed during your consultation.

The suitability of LASIK depends on your individual case. A final decision can only be made after a refractive surgeon has reviewed your medical history, recent eye examination reports, and corneal imaging.
