Frequently Asked Questions

NO. There is no pain during or after the procedure. The patient may feel some pressure over the eye which lasts for a few seconds.

Normally, twice a year is recommended. But in some cases, one may need to visit more for consultation and check-ups.

Eye floaters are tiny specks and spots that keep floating in your field of vision. Usually, they are harmless, but it is recommended that one must consult a doctor if the phenomenon occurs often.

The most common options available are:

PRK : It is being used less commonly now days.

LASIK: This is most popular form of laser treatments.

LASEK (or EPI-LASIK) : This newer form of treatment may be suitable in some selected patients with very high power.

The refractive errors may be treated by either of the following ways:

Glasses: This is the simplest and most popular way of correcting refractive errors.

Contact lens: This option is cosmetically much better. However, it requires though maintenance and cleaning of the contact lenses, and regular eye checkups. There is also a sight risk of allergy and infection to the eye, if the contact lenses are not cleaned properly.

Refractive laser surgeries: Get rid of the need for glasses and are increasingly becoming popular with the advent of safer and more predictable laser treatments.

Left untreated, the cataract progresses and the lens becomes increasingly opaque. The rate at which cataracts develop varies from person to person, but the end result is always the same: blindness. Furthermore, more advanced cataracts are more difficult to remove: the surgery takes longer and the level of risk increases.

A cataract is a cloudiness of the eye's natural lens, which lies between the front and back areas of the eye, directly behind the pupil.

Intra Ocular lens (IOL) is a tiny transparent convex lens to replace the cloudy cataractous lens in the eye. It is made of different materials like PMMA (polymethyl methacrylate, a harmless plastic substance), Silicon & Acrylic (Hydrophillic & Hydrophobic). Unlike contact lens, an IOL stays permanently in the eye and does not cause irritation. A foldable IOL is inserted into the eye through a device called IOL Injector through a small incision of 2-3 mm dimension.

At Drishti Eye Centre we use the best quality Foldable Imported IOL’s of reputed multinational companies.

Advantages of IOL:-

Since the lens is placed inside the eye, most patients do not need glasses for clear distance vision. But patient has to wear reading glasses for near and intermediate vision tasks.

  • Images are clear and of the same dimension without distortion.

  • Full vision returns quickly.

  • Normal field of vision.

Lasik involves raising a very thin corneal flap with the help of a special automated and very precise blade. After this the excimer laser treated is applied to the rest of corneal surface to change its shape and thus correct the refractive error. The parameters used for conventional Lasik are based on the refractive error of the patient. The raised flap is then positioned back, where it sticks without the need of any suture.

In younger persons, the lens has the capacity to increase its power to focus for nearer objects (accommodation). Presbyopia is a part of normal aging process, where the lens progressively loses this capacity of accommodation. The distance vision may be normal, but the near vision becomes blurred with age greater than about 40-45 years. This is correct by wearing reading glasses (plus) for the near work. One must remember that refractive laser surgeries only correct the refractive error (myopia, hypermetropia and astigmatism), but do not correct the presbyopia.
