Cataract FAQs

1)  What is cataract surgery all about?

Cataract surgery is removal of natural lens which has developed opacification and replaced with intraocular lens.

2)  What causes cataract?

Normally natural lens is transparent, as age increases lens becomes lens transparent due to breakdown of lens proteins. Cataract is also caused by diabetes and injury, prolonged exposure to sunlight, long term usage of steroids and some inherited disorders.

3)  What are three types of cataract?

Nuclear sclerotic cataract

Cortical cataract

Posterior subcapsular cataract

4)  Are cataracts painful?

Usually cataract does not cause pain except when they are left untreated for long-time, they cause pain, redness, watering and sensitive to light.

5)  Is cataract surgery painful?

Cataract surgery is not a painful procedure but the patient may feel apprehensive. To overcome that local anaesthetic block or eye drops are instilled in the eye.

6)  Does cataract surgery give you 20/20 vision?

Most of the patients get 20/20 vision after cataract surgery except in condition like previous high refractive errors, diabetes, glaucoma, corneal scars and macular degeneration.

7)  Does cataract grow back?

Once cataract is removed it cannot grow back.

8)  How fast does cataract grow?

Development of cataract varies, based on individual and other factors. It can vary between the eyes of same individual. Mostly age-related cataract develops slowly. In young individuals cataract develops due to injury, exposure to sun light, in diabetic patients cataract grows rapidly.

9)  Is cataract surgery safe?

Cataract surgery is very common and safe surgery. It gives successful outcome except in few conditions like corneal scars, macular degeneration, diabetes and glaucoma.

10) Can you see cataract in the mirror?

Cataract are usually not visible but if they are left untreated for a long-time they look white which can be seen by others or themselves in the mirror.

11) When should cataract be removed?

Cataract removal is advised to patients when there is difficulty in doing daily activities, driving and difficulty in seeing objects.

12) Can you get rid of cataract without surgery?

There is no cure for cataract with medications or home remedies. Once cataract is developed surgery is the only option.

13) What causes a cataract to grow faster?

Cataract grows faster in individuals who had trauma, diabetes, prolonged exposure to sunlight, smoking, radiations and systemic conditions like inflammations and long-term use of steroids and certain medications.

14) What are disadvantages of cataract surgery?

Cataract surgery is safest procedure with high success rate, rarely complications can occur such as infection, left over fragments, lens capsular tear, increased eye pressure, swelling of the retina.

15) What happens if a cataract is left untreated?

If a cataract is not treated it will lead to loss of vision and it affects quality of life. It may also cause secondary complications which will affect the health of the eye. Cataract is the most common cause of blindness.

16) Is it better to have cataract surgery early?

Yes, it is better to have cataract surgery early in immature stage as this reduces the duration of surgery and lessen the recovery time. By early surgery, individual can avoid significant visual impairment associated with mature and hyper mature cataract.

17) How bad does cataract have to be qualifying for surgery?

Surgery can be advised when patient has difficulty in night vision, driving, glare halos, no improvement with glasses.

18) Are floaters a sign of cataract?

No, Floaters are not signs of cataract.

19) How long is recovery after cataract surgery?

Recovery after cataract surgery is short. Any pain redness, discomfort disappears within couple of days. Full recovery may take 2 to 4 weeks. Recovery time varies from person to person depending on patient’s health and immunity.

20) What are two types of cataract surgeries?

Two types of cataract surgeries are:

1. Manual small incision cataract surgery (SICS)

MSICS: Small incision is made with blade and incision is widened to implant        the intraocular lens. This is suture less surgery.

2. Phacoemulsification: small incision is giving at the edge of cornea creating an opening through membrane surrounding the lens followed by inserting ultrasonic probe into the opening to break the lens into pieces and removed. Later on, foldable intraocular lens is placed. This incision is very small and recovery is much faster.

21) What is the safest cataract surgery?

Phacoemulsification is the safest cataract surgery as it has small incision, less astigmatism and faster recovery time.


1) What is LASIK?

LASIK is a type of refractive surgery for correction of myopia, hyperopia and astigmatism. Lasik – laser in-situ keratomileusis

2) How long does LASIK outcome last for?

LASIK surgery involves ablation of the cornea or reshaping, which is permanent.

3) Is LASIK permanent?

Yes, LASIK is permanent. LASIK makes permanent changes to cornea.

4) Will I still need glasses after lasik?

No, glasses are not required in most of the cases, as LASIK makes desired refractive changes on the cornea.

5) Can LASIK cure astigmatism?

Lasik can cure astigmatism up to 4.0 D.

6) What age is best to get LASIK eye surgery?

Age is an important factor for LASIK surgery. Patients should be above 20 yrs of age and with stable refractive power for at least 1 year.

Cornea – FAQs

1. What is Cornea and its functions?

The Cornea is the clear outer layer at the front of the eye. The Cornea helps your eye to focus light so you can see clearly. The Cornea is the crystal clear (transparent) tissue that covers the front of the eye. It works with the lens of the eye to focus images on the retina.

2. What happens if Cornea is damaged?

Any injury to a deeper layer of the Cornea, the healing process takes longer and may result in the following symptoms: blurred vision, pain, redness, sensitivity to light and tearing. More serious injuries will produce Corneal scarring, which can cause distorted vision or even dramatically impaired vision.

3. Can Cornea repair itself?

The Cornea can recover from minor injuries on its own. But, if a scratch causes a deep injury to the Cornea, it will take longer time to heal.

4. What are the five layers of the Cornea?

The Corneal layers include Epithelium, Bowman’s layer, Stroma, Descemet’s membrane, and Endothelium.

5. Can Cornea grow back?

Your Cornea usually heals itself after most minor injuries or infections. But during the healing process, you might notice symptoms like: pain and blurred vision. Any injury to a deeper layer of the Cornea, the healing process takes longer and may result in the following symptoms: blurred vision, pain, redness, sensitivity to light and tearing. More serious injuries will produce Corneal scarring, which can cause distorted vision or even dramatically impaired vision.

6. How does Cornea get oxygen?

Cornea gets oxygen from tears in the form of dissolved oxygen.

7. Can you go blind from corneal abrasion?

Mostly simple abrasion does not cause any major problem unless associated with infection.

8. Why is the Cornea slow to heal?

Minor Corneal abrasions heal quickly, usually within two days. More serious wounds take longer to heal and can cause irritation, pain, tearing, and redness. If the Cornea becomes deeply scarred it can cause vision problems.

9. Can Cornea cause blindness?

Corneal opacities can cause anything from minor irritation to vision problems and even blindness. In fact, Corneal problems are the fourth leading cause of blindness (after glaucoma, cataracts, and age-related macular degeneration).

10. What does scratched Cornea feel like?

Scratched Cornea symptoms might include significant discomforts, red eyes, tearing, blurry vision and sensitivity to light.

11. At what age keratoconus stops?

There is no “real” age at which keratoconus stops progressing. In general it tends to be more aggressive in younger people and slowly progressive in older people.

12. Can Corneal haze be corrected?

It can be corrected by drugs, but sometimes may need surgery.

13. What can cause Corneal damage?

Corneal diseases include keratitis, ocular herpes, Corneal dystrophy, herpes zoster & others can cause damage to Cornea.

14. How painful is a Corneal transplant?

On the day of Cornea transplant, you will either be given a sedative to help you relax and a local anesthetic to numb your eye, or you’ll be put to sleep. Either way, you shouldn’t feel pain after surgery, but you may feel pain for few hours to days depends on the cause of surgery.

15. What happens if Keratoconus is left untreated?

If the Loss of vision due to Keratoconus cannot be treated with glasses, it may need surgery.

16. Can keratoconus reverse itself?

No, but as the age increases progression decreases.

17. Is Keratoconus classified as a disability?

A person is considered to be disabled if the remaining vision in the better eye after best correction is 20/200 or less and in advanced cases keratoconus patient may become disabled but you can avoid by appropriate surgery at appropriate time.

18. Why is my vision suddenly cloudy in one eye?

Blurring of vision in one eye can be due to refractive errors, dry eyes, migraine, optic neuritis, eye trauma, inflammation and vein occlusion.

19. Who is a candidate for Corneal transplant?

Advanced Corneal ulcer, advanced keratoconus, Corneal opacity affecting vision.

20. How do I measure the thickness of my Cornea?

One can measure corneal thickness by Corneal topography, Anterior OCT and pachymetry.

21. Does glaucoma affect the Cornea?

If pressure in eye increases more than 40 mm Hg, then Cornea becomes cloudy leading to decrease in vision.

Dry Eyes – FAQs

Symptoms and causes

Dry eye occurs when there is inadequate tear volume or function resulting in an unstable tear film

The various causes are

  • Age related
  • Exposure to dry and windy air
  • Secondary to diseases like diabetes, thyroid, rheumatoid arthritis
  • Long term usage of topical eye drops like anti-glaucoma, anti-allergic eye drops
  • Contact lens usage
  • Oral drugs like antihistamines, antidepressants, diuretics etc.
  • Pregnancy and menstrual disorders due to hormonal disturbances
  • Deficiency of vitamin A
  • Disorders of eyelids like entropion, lid retraction, proptosis etc.
  • Increased digital screen exposure
  • Post cataract surgery, post LASIK surgery.


Symptoms depend on the severity of the disease and may vary from person to person, Common symptoms include

  • Redness of eyes
  • Itching and burning sensation
  • Watering
  • Grittiness or foreign body sensation
  • Pain and strain in the eyes
  • Heaviness of eyes
  • Stringy eye discharge
  • Blurred vision

Does dry eye go away?

Dry eyes caused due to certain conditions are temporary like contact lens usage, environmental factors. So, by stopping the usage and change of lifestyle dry eye can be treated easily. But mostly dry eye is a chronic condition. With the help of doctor’s advice and by using eye drops, and changes in lifestyle we can treat dry eye.

Can dry eye cause blindness?

Dry eye mainly affects the delicate layer of the eyes i.e the cornea. This may lead to corneal Infection, ulceration and corneal opacity which may cause decreased vision.

How do you permanently treat dry eye?

Lifestyle modification and medications can help in treatment of dry eye.

  • Lifestyle modifications like usage of humidifier, taking foods rich in vitamin A, cautious usage of contact lens, decreased digital screen exposure can relieve some symptoms of dry eye.
  • Those who use digital screen for long periods should follow the 20/20 rule. For every 20 minutes we need to take rest and look at an object which is 20 feet away for a period of 20 minutes. This may relieve the eye strain.
  • Usage of artificial tears. And in severe cases usage of steroid drops and cyclosporine drops. By doing a simple procedure like punctual occlusion we can prevent the tear film drainage and decrease dry eye symptoms.

Can dry eye make cataract worse?

Cataracts cause gradual loss of vision. If the patient also has dry eye, he will be complaining of redness, watering, itching and decreased vision associated with cataract. Usually these two problems are age related and mostly seen in elderly people.

Does cataract make eyes dry?

Cataracts are usually associated with dry eyes. But cataract surgery can cause dry eye due to disturbances in the tear film stability. It is more in case of SICS surgery when compared to phaco surgery. But in most cases, it is temporary and can be treated with medications.

Can dehydration cause dry eye?

Yes, decreased intake of water in the body causes dehydration. It causes dry mouth, dry skin, headache, decreased sweat production, dry eyes and other symptoms.

So, severe dry dehydration causes redness, watering and burning sensation in the eyes – Drink lots of water, intake of ORS, or by taking intravenous fluids we can treat dehydration.

By using artificial tears, we will be able to treat dry eye symptoms.

Q. How is ICL surgery done?

A. Under topical anesthesia ICL lens is implanted into anterior chamber and with ICL tucker the four haptics of ICL are tucked under iris into the sulcus without damaging lens capsule.

At the end, viscoelastic substance is washed out & incisions closed.

Q. How long it takes to recover from ICL surgery?

A. After 2-3 hrs of surgery, patient can have visual recovery.

Q. Is ICL better than PRK?

A.ICL is better than PRK in thin corneas, high myopia & severe dry eyes with high myopia.

Q. Which surgery is best for myopia?

A. For mild to moderate myopia LASIK / PRK is better.

For moderate to severe myopia and dry eyes ICL surgery is better.


Q. How long does it take to recover from corneal cross linking?

It will take about 2-3 days to recover from symptoms due to light sensitivity. It might take maximum of week.

Q. How effective is cxl?

It is now widely agreed that CXL is only effective treatment for keratoconus to halt the progression. 95% success rate reported in major studies. Few might require re-treatment.

Q. Does cross linking improve vision?

CXL is not a procedure done to improve the vision. It is primarily done to increase the mechanical strength of cornea and slow down the progression.

Q. How much does CXL in keratoconus costs?

CXL for reach eye costs about Rs. 32,000.

Q. Does cross linking stop keratoconus?

Keratoconus usually progresses in 20s and halts by the end of 30. Its progression is observed in early stages. CXL slowdowns the progression in majority of cases.

Q. Can CXL be repeated?

Yes it is possible to repeat CXL after 6 months if needed.

Q. AT what age keratoconus stops?

It is generally considered that keratoconus stops by the age of 40.

Q. What happens if keratoconus is left untreated?

As KERATOCONUS progresses cornea will get thinner and thinner. The thinned bulged cornea leads to low vision often not corrected with spectacles or contact lens. It might even lead to scarring.

Q. How do you slow down keratoconus?

Avoiding rubbing eyes, taking proper treatment for allergic conjunctivitis, regular follow up with ophthalmologist, undergoing CXL when advised will slow down KERATOCONUS and its complications.

Q. What is considered severe keratoconus?

When in keratoconus / corneal thickness <200 K reading> 55.00, present central scars, Refraction is not possible. It is considered severe keratoconus if any one of the above symptoms present.

Q. Does keratoconus get worse over time?

If left untreated keratoconus can progress and get worse. Treatment by CXL halts the progression and prevents worsening of the condition.

Q. How do I know if my Keratoconus is progressing?

Once diagnosed to be a Keratoconus patient, Frequent scheduled review visits to ophthalmologist helps to document progression of Keratoconus through clinical examination, Topography and pachymetry scans. Gradual decrease in vision and frequent change of spectacles should alarm specialist review especially in teenage patients with astigmatism.

Q. Is Keratoconus an autoimmune disease?

No, keratoconus is not an auto immune disorder. It has multifactorial pathogenesis. But it is associated with Auto immune disorders like rheumatoid arthritis, Ulcerates colitis, Thyroiditis etc.

Q. What can make keratoconus worse?

Ans: Continuous rubbing of eyes, Noncompliance of allergic conjunctivitis treatment, Improper fitted contact lens, laser refractive surgeries worsen keratoconus.

Q. Can Lasik fix Keratoconus?

No, Lasik / PRK reshape cornea by thinning down the tissue. In keratoconus removing tissue inherently weakens the cornea further which deteriorates the condition.
