LASIK is an acronym for Laser-Assisted in situ Keratomileusis. It is the most popular and trusted laser eye surgery for surgical treatment of Myopia, Hyperopia and Astigmatism. It is a completely pain-free treatment and takes only 15 minutes for both eyes.

LASIK uses a laser to change the shape of the cornea. In the myopic eye, the cornea and lens are too curved and focus the image to a point in front of the retina, the image then appears blur. Laser slightly flattens the cornea which is the curved rounded front surface of the eye. The image is then clearly focused on the retina. In the hyperopic eye, the cornea and lens are too flat and focus the image to a point behind the retina, leading to the image appearing blur. After laser correction the cornea is slightly more curved; the image is then clearly focused on the retina. The result is that the hyperopic patient can see clearly for distance after LASIK treatment.

In Astigmatism, the eye is oval like a football, and not spherical. The image is formed at two different points inside the eye. In the treatment of astigmatism, irregularities in the shape of the cornea are smoothened to even out the focusing power.

Requirements for candidature for LASIK

• You should be at least 18 years old since the refraction of people younger than 18 usually continues to change.
• You should not be pregnant or nursing as these conditions might change the measured refraction of the eye.
• Your eyes must be healthy and your glass prescription stable.
• You should be in good general health.
