FREQUENTLY ASKED QUESTIONS
Q1. WHAT IS CATARACT AND WHY DOES IT HAPPEN?
Cataract is the cloudiness of the crystalline lens of the eye leading to inability of light to pass through the visual system of the eye.
Cataract is most commonly an age related change similar to greying of hairs. Such cataract is called “Senile Cataract.” However cataract can also occur due to various other causes in children (Paediatric cataract) and also in younger adults due to causes like trauma or injury, diabetes, drugs etc.
Q2. WHAT ARE THE COMMON SYMPTOMS OF CATARACT?
Common symptoms of cataract include
- Blur or foggy vision without pain
- Glare during night driving
- Ability to read without glasses
- Haloes around light
- Double or multiple images
Q4. HOW CAN I CONFIRM THE DIAGNOSIS OF CATARACT?
If you feel you have any of the above mentioned symptoms or any other symptom that arouses the suspicion of cataract, you need to get an eye testing done and get it confirmed by an eye specialist. Complete eye check up is necessary to confirm the diagnosis of cataract or any other eye disease.
Q5. WHAT IS THE TREATMENT FOR CATARACT?
Significant cataract which is causing any of the above mentioned symptoms or any other eye symptom can only be treated by surgery. If the cataract is very early or insignificant, it can be observed.
Q6. WHEN IS THE RIGHT TIME TO UNDERGO CATARACT SURGERY?
Patients with cataract can undergo cataract surgery whenever blurred vision makes normal activities difficult for them.
Q7. WHAT DOES LASER CATARACT SURGERY MEAN?
Laser cataract surgery means using laser or ultrasonic energy to remove the cataract along with implantation of intraocular lens inside the eye. It is most commonly performed under anaesthetic drops, one eye at a time and without using any stiches or sutures. Laser cataract surgery is considered best because it gives predictable and consistent outcomes and is also very safe.
Q9. WHAT DO I NEED TO KNOW ABOUT INTRAOCULAR LENS?
Intraocular lens are artificial devices that are implanted inside the eye once the cataract is removed. It works as a substitute for the normal lens.
Various types of intraocular lenses are available which can be a routine foldable or non-foldable lens or a premium lens like Aspheric lens, Toric lens, Multifocal lens, Multifocal toric lens or a Trifocal lens. Non-foldable lens needs minimum cut of 5 mm or more for it to be implanted while the foldable and the premium lenses can be implanted through cuts that are less than 2 or 3 mm. Thus, following foldable and premium lens implantation, recovery is faster and better.
Q12. WHAT IS AN ASPHERIC FOLDABLE LENS?
Aspheric lenses are lenses which are implanted based on the asphericity of the eye. These lenses ensure better quality of vision especially in the dark by improving the contrast sensitivity of the eye.
Q13. WHAT IS A MULTIFOCAL LENS?
As the name suggests, a multifocal lens is capable of focussing at variable points thereby allowing patients to see distant, near and intermediate distance without the help of spectacles. It is very comfortable for individuals who work on the computer or those who have been using progressive glasses. Implantation of multifocal lens usually ensures spectacle free vision at all possible distances.
Q14. What is MICS?
MICS or Micro Incision Cataract Surgery involves performing Phaco emulsification through an incision which is less than 2 millimeters. Thereafter a MICS intraocular lens is implanted inside the eye.
Q15. WHAT IMPORTANT PREPARATIONS ARE REQUIRED PRIOR TO CATARACT SURGERY?
The following tests need to be done prior to cataract surgery -
- using Optical Biometer : To take various measurements that help us determine the power of the intraocular lens to be implanted in the eye.
- Blood tests and Physician Fitness
LASIK, Femto LASIK and ICL
Laser eye surgery procedures for elimination of glasses or eye number includes surgical procedures like FEMTO –LASIK, LASIK, SMILE, PRK, Topoguided PRKetc which are effectively used to remove dependence on glasses.
- FEMTO LASIK – Also called as “Bladeless LASIK” involves use of two different kinds of laser. First, Femto second Laser is used to create the flap, instead of a blade and then Excimer laser is used to reshape the cornea in order to remove the glass number. The flap is then put in place. The procedure is performed under anaesthetic drops and both eyes are treated at the same sitting.
- LASIK – involves using a Microkeratome to create a hinged flap on the cornea followed by application of laser rays on the corneal bed to remodel the cornea and replacing the flap. The procedure is performed under anaesthetic drops and both eyes are treated at the same sitting.
- SMILE – Small Incision Lenticule Excision(SMILE) involves use of Femto second laser to remove a thin layer of corneal tissue from within a pocket created within the cornea.Useful for thin corneas where LASIK or FEMTO LASIK are not permissible.No blades are used here. The procedure is performed under anaesthetic drops and both eyes are treated at the same sitting.Postoperative recovery is much faster.
- PRK – involves using laser to remodel the cornea without using the Microkeratome. Useful for thin corneas where LASIK or FEMTO LASIK are not permissible. PRK can also be done, Topo guided in irregular corneas
- Presbyopic LASIK – LASIK performed to treat patients with presbyopia along with other refractive errors. It involves meticulous planning but can give excellent results and make patients very happy
– Implantable collamer lens are put inside the eye for patients who have very high numbers and cannot be treated by Laser Refractive Surgery. This surgery is done, one eye at a time and need proper measurements to be done to adequately size the implant. Read More...

Retinal surgery - Vitrectomy, Retinal Detachment, Intraviteal injections
Management of Retinal diseases has changed drastically from about 2005 because of better diagnostic instruments such as OCT, better medicines such as Anti VEGF (Avastin, Lucentis) and high speed, sutureless vitrectomies.
At Eye Life, we use OCT machine to diagnose the disease in the retina. It scans the retina in a matter of few seconds and neither involves any injection nor any eye patch after the procedure. One can continue regular duties after the test. OCT uses laser to provide a CT scan like picture of the retina wherein the problem at the microscopic level can be seen.
Many retinal diseases can nowadays be treated by drugs such as Anti VEGF (Avastin, Lucentis, Accentrix, Eylea), Triamcinolone acetonide and Ozurdex. These medicines are injected near the retina by a fine needle under the effect of anaesthetic eye drops making the process relatively painless.
Lasers are commonly utilised to treat retinal diseases such as diabetic retinopathy and complications in the eye due to raised blood pressure (BRVO, CRVO). This machine can be used during retinal surgeries which are laser assisted as well as in consulting room for laser treatment. Laser treatment in the opd is often given in the sitting position and doesn't require any injection or eye patch after laser treatment. Patients can mostly resume regular duties on the same day itself after laser treatment.
At Eye Life, experience of America trained retina specialist with more than 15 years experience in ophthalmology along with advanced instruments such as Retinal microscope, Wide angle retinal viewing system, High speed sutureless vitrectomy unit and laser machine, enables to deliver consistent results. The ability to do key-hole surgery which doesn't require stitches in the eye leads to quick recovery after the surgery. All surgical problems like Diabetic Retinopathy, Retinal Detachment, Vitreous Haemorrhage are managed very effectively and safely, at Eye Life.
Cornea surgery - DSAEK, DALK, CXL, Boston Keratoprosthesis, Stem cell transplan
Corneal surgeries consists of a variety of different surgeries on the cornea and ocular surface. At Eye Life,™ our Cornea, dry eyes and ocular surface specialist Dr Sushmita Shah, having undergone fellowship training at prestigious institutions like Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, USA and at L V Prasad Eye Institute, Hyderabad is an expert at performing myriad of corneal surgical procedures including advanced corneal transplantation (Keratoplasty) techniques like – DSAEK, DSEK, DALK, Boston Keratoprosthesis (for severe dry eye), Limbal Stem Cell Transplantation (SLET and other techniques), Collagen cross linking (CXL), INTACS, Amniotic membrane transplantation, Anterior segment reconstruction, ocular surface reconstruction, pterygium etc.
Corneal transplantation or Keratoplasty are surgeries done to remove the abnormal cornea and replace it with a normal cornea taken from a donor. The various reasons for removing the cornea include Keratoconus, Cornea infections or ulcers, Corneal edema after cataract surgery, Corneal dystrophies etc. Various types of corneal transplantation or keratoplasty techniques include full thickness transplant or penetrating keratoplasty(PK), partial thickness or lamellar keratoplasty(LK) like Descemet Stripping Automated Endothelial Keratoplasty(DSAEK), Descemet Stripping Endothelial Keratoplasty (DSEK), Deep Anterior Lamellar Keratoplasty(DALK). Earlier, all corneal transplants used to be PK which included replacing all the layers of the cornea irrespective of which layer of the cornea is has the disease with a normal cornea and securing it with stitches or sutures. In partial thickness or lamellar procedures, only the diseased layer of the cornea is replaced by a similar layer from the donor cornea. Thus, DALK is performed in eyes with abnormal corneal stromal disease like Keratoconus, Corneal scars, Stromal corneal dystrophies etc while DSAEK/DSEK is performed in eyes with abnormal corneal endothelium like Fuch’s endothelial dystrophy, post cataract surgery corneal edema etc. The advantages of DSAEK and DALK over PK includes higher long term graft survival, early visual rehabilitation, better visual outcomes etc.
Boston KeratoprosthesisThis revolutionary device was designed and developed by Dr Claes Dohlman from the Massachusetts Eye and Ear Infirmary, Boston, USA and has got US FDA approval for the treatment of severe dry eyes. The various indications for Boston Keratoprosthesis impantation include – End Stage Dry Eye Disease, Multiple failed corneal transplantation or Keratoplasty, Chemical injury, Limbal stem cell deficiency etc. Also called as the artificial cornea this device works in eyes where Keratoplasty does not work or has failed to work.
Collagen Cross Linking (CXL) Collagen cross linking is a revolutionary treatment for Keratoconus which entails application of Riboflavin eye drops on the abnormal cornea followed by exposure of the cornea to Ultraviolet (UV) rays. This treatment helps in increasing the number of collagen cross links within the corneal stroma thus preventing progression of abnormal corneal protrusion and irregularity.
INTACSINTACS are semicircular ring segments that are implanted within the corneal stroma in order to correct the abnormal corneal shape in Keratoconus. INTACS may be done together with CXL or at different sittings. While CXL helps in stopping the progression of Keratoconus, INTACS help in reducing corneal irregularity and patients can have good spectacle free vision.
Anterior Segment ReconstructionAnterior Segment Reconstruction encompasses surgical procedures which help in repairing abnormal structures of the anterior segment or front of the eye which includes structures like, iris, pupil, lens etc. The procedure for iris repair is called iridoplasty, the procedure for pupil repair is called pupilloplasty. We can also repair or reposition abnormally placed intraocular lens with fairly good efficacy.
Stem Cell TransplantationStem Cell Transplantation surgery involves transplantation of healthy stem cells from the healthy ocular surface to abnormal ocular surface. The commonest indication for Stem Cell Transplantation is limbal stem cell deficiency. In a recently described technique called SLET – Simple Limbal Stem Cell Transplantation, limbal biopsy is taken from the healthy eye and transplanted directly onto the abnormal ocular surface and secured with the help of fibrin glue. This technique is easy to perform and is also very cost effective.
Amniotic membrane transplantationAmniotic membrane is a biological tissue which is extracted from the human placenta. It is now being extensively used in ocular surface surgery in situations like chemical injury, ocular surface reconstruction, SLET etc. It helps in better healing of the ocular surface with minimal scarring.
Pterygium SurgeryAt Eye Life™ we perform advanced techniques of pterygium surgery so that chances of recurrence are minimal. These techniques include use of a conjunctival autograft, amniotic membrane, fibrin glue etc.
