Corneal ectasia is an umbrella term for conditions in which the cornea progressively thins and bulges forward, disrupting its smooth refractive surface and causing worsening, irregular vision. Keratoconus is the most common form. Post-LASIK ectasia and pellucid marginal degeneration are rarer but clinically important variants. Understanding ectasia explains why glasses stop working and what can be done.

Contact lenses are the most natural, unobtrusive form of vision correction available, but they do require a proper fitting and good habits to wear safely. If you're considering lenses for the first time, here's everything you need to know before your first appointment.

An irregular cornea is one whose surface deviates from the smooth, spherical shape needed for clear focusing. This irregularity scatters light in multiple directions, creating a blurry, distorted image that no spectacle prescription can fully correct. The conditions that cause it range from keratoconus to corneal scarring to post-surgical complications. Understanding why standard correction fails, and what does work, is the first step.

After learning about Ortho-K, most parents have two immediate questions: does it work, and is it right for my child? The first question has a clear answer, the clinical evidence is strong. The second requires an individual assessment. Here's how we think about Ortho-K candidacy.

Dry eye is the single most common reason people stop wearing contact lenses. The lenses feel uncomfortable by midday, vision fluctuates, and the eyes feel gritty and tired. Many patients are simply told 'contact lenses aren't for you' and switched back to glasses. But this is usually not necessary, the right lens choice makes an enormous difference.

Scleral lenses have transformed the lives of patients who thought clear vision was permanently out of reach, patients with keratoconus, post-surgical corneas, severe dry eye, and other complex conditions. They are not well known in India despite being available for over two decades. Here is a complete guide to what they are, how they work, and who benefits from them.

LASIK is the most commonly performed elective surgery in the world, with a generally high satisfaction rate. But 'generally high' still leaves a significant number of patients with outcomes they didn't expect, persistent blur, worsening vision years later, glare and halos that weren't there before, or a diagnosis of post-LASIK ectasia. If you're in this group, this is for you.

Blurry vision that glasses can fix, halos at night, frequent prescription changes — these are classic early signs of keratoconus that go undiagnosed for years.

Childhood myopia progresses because the eye is still growing. Here&amps what causes it, why it matters for long-term eye health, and what can be done to slow it down.

Orthokeratology lenses are worn overnight and correct vision while the child sleeps, no glasses or contact lenses during the day. Clinically proven to slow myopia.
