HYDERABAD: There was a time when myopia (short-sightedness), a defect in which one can see near objects clearly while distant objects go blurred, was considered to be hereditary. While the conventional belief still holds sway in majority of cases, there is also a growing acceptance among specialists that lifestyle too plays a vital role in causing myopia. An interaction session between patients and doctors at a public education forum on myopia organised by L.V. Prasad Eye Institute (LVPEI) at its premises on Sunday, threw-up such fascinating facets of myopia. Unproductive timeThe LVPEI doctors, however, cautioned that patients should make an ‘educated’ choice, before opting for treatment and not to get swayed by the hyperbole. “Studies in Hong Kong and China indicate that 70 per cent of children below 18 years there have myopia. The study said that children spend less than 30 minutes of outdoor activities in a week indicating that they spend most of the time in front of computers, television or books,” said LVPEI ophthalmologist Prashant Garg. While there are limitations in the prevention aspect of myopia, a host of treatments abound for correcting the defects from the condition. Glasses, contact lenses and the modern laser (LASIK-Laser-Assisted In-Situ Keratomileusis) treatment being the most common methods of treating myopia. With changing lifestyles, growing importance on ‘looking good’ and niggling problems with contact lens, Lasik is fast emerging as the most preferred choice to rectify myopia. “Lasik is appreciated by those who are fed up with the limitations of glasses and contact lens. However, it’s not like you can just walk in and out after Lasik treatment. Not all are eligible for laser treatments and patients should be wary about it,” Dr. Garg pointed out. In general, doctors said that Lasik is recommended for patients with mild to moderate degree of myopia and more caution needs to be exercised while operating on patients with far-sightedness or hyperopia. “In Lasik, the curvature of the cornea is reshaped using laser. It is given only to persons above 18 years and having unchanged spectacle power for at least one year,” another ophthalmologist Varsha Rathi said.
