CATARACT AND RETINA

HOW DO I GET TO KNOW IF I HAVE CATARACT?

In early stages of cataract, you may either not have any symptoms or experience increased glare and reduced night vision. Only when cataract becomes mature, you will see a white spot in centre of the eye.

WHAT ARE THE TREATMENT OPTIONS AVAILABLE FOR CATARACT?

HOW IS THE CATARACT SURGERY PERFORMED?

Cataract surgery is done by phacoemulsification (LASER). It is a painlesss, 7-10 minutes procedure which does not require any injection. Also there is no patch applied on the eye after surgery. You can go home immediately after the surgery and get back to your routine work the same day.

4) A tidy bath with hair and face wash is a must on the day of surgery.

WHAT ARE THE POST-OPERATIVE INSTRUCTIONS AFTER CATARACT AND RETINA SURGERY ?

1) No head bath for 4 days, however, one can wipe face and head with wet cloth. Bath from neck down is fine.
2) Protective glasses only for outdoor use, mainly to prevent dust entry and inadvertent trauma to the operated eye.
3) Sleeping in the night with protective glasses or shield on is recommended to prevent inadvertent eye trauma.
4) No indoor use of protective glasses is necessary, except when one is cooking or is in close proximity to gas.

LASIK

WHAT IS LASIK SURGERY?

It is surgical procedure performed to get rid of glasses permanently. It is cool (non-thermal ) laser energy to modify the cornea (outer-most layer the eye ) so that images are clearly focused on the retina. LASIK and PRK are the two broad categories of laser vision correction.

ARE ALL PATIENTS WEARING GLASSES AND CONTACT LENSES CANDIDATES FOR LASIK SURGERY?

WHAT IS DONE IN PRE-LASIK WORK UP?

Pre –lasik work up includes detailed ocular and systemic history taking, refraction (number checkup), intraocular pressure measurement, dilated retinoscopy, anterior segment and retina evaluation, corneal topography and specular microscopy followed by a detailed counseling session.

IS LASIK SURGERY RIGHT FOR ME?

If pre-lasik tests and ocular examination is normal and if you are motivated to have glass free vision, lasik is right for you.

WHICH TYPE OF REFRACTIVE ERRORS CAN BE TREATED?

We can treat nearsightedness (myopia), farsightedness (hyperopia), cylindrical powers (astigmatism) and reading numbers (presbyopia).

IS THERE ANY AGE LIMIT FOR LASIK SURGERY?

Lasik is normally done after age of 18 years once the refraction stabilizes. However, we do perform lasik in children with uniocular lazy eyes (anisometropic amblyopia). Lasik can be done even after age of 40 years as our machine also corrects presbyopia (reading numbers)>

WILL I HAVE 6/6 VISION AFTER LASIK SURGERY?

You will have reasonably good vision immediately following lasik .After an initial healing period of approximately 2-3 weeks or lesser; vision is restored to 6/6.

IS LASIK A SAFE SURGERY?

Since laser is delivered on the outer most layer of the eye without entering the eyeball and with latest machine we have, lasik is a completely safe surgery.

CAN I UNDERGO LASIK IF I HAVE THIN CORNEAS?

A combination of tissue saving software and thinner blades allow lasik in thin corneas. If lasik is not suitable, TransPRK , ICL etc are other options that are available.

CAN I UNDERGO LASIK IF I HAVE HIGH NUMBER?

Yes if pre-lasik tests are normal and if the corneal thickness permits laser treatment.

CAN LASIK BE DONE AFTER 40 YEARS OF AGE?

Hybrid presbyopia micromonovision lasik allows removal of distance and near numbers even after age of 40 years.

HOW WILL I KNOW WHICH LASER PROCEDURE IS BEST FOR ME?
