 New procedure to correct eye defect
An eyecare hospital in Coimbatore has introduced a minimally invasive medical procedure that could avoid the need for eyeglasses, especially reading glasses.
'Conductive Keratoplasty' (CK) would correct the most common eye problem, affecting those who have crossed 40 years and suffering from 'presbyopia', a natural ageing condition where the crystalline lens inside the eye loses it elasticity and thus fails to focus for near objects, said Dr K Ramamurthy, medical director of Eye Foundation.
Stating that the advanced Lasik procedure normally did not satisfy people aged over 40 years due to its limitations of not being able to correct near vision problem, he said radio frequency (RF) was a form of electrical energy in the frequency range of 300 KHz to one MHz. The nearvision CK involved controlled release of RF energy instead of a laser of scalpel, to reshape the cornea and correct vision in people over 40 years.
It was the way RF was absorbed in the body that has made it one of today's most advanced surgical techniques and replacing lasers in everything from prostate cancer therapy to cardiovascular procedures, Ramamurthy said.
Stating that the procedure took less than three minutes and done in-office with only topical anesthesia, he said using a tiny probe as thin as a human hair, controlled RF energy as applied in a circular pattern, causing constriction, almost like tightening a belt, which gently increased the curvature of the eye to improve near vision, Ramamurthy said.
