Best Corneal Surgery in Alwarpet, Chennai

The cornea is the dome-shaped part of your eye that is responsible for your vision. Problems in the cornea can lead to several complications such as vision deterioration or even vision loss. You must visit ophthalmology hospitals in Alwarpet if you experience any symptoms of corneal damage. 

What is corneal surgery?

Corneal surgery is performed by a corneal detachment specialist in Chennai to restore vision or improve a damaged cornea. Corneal surgery is most successful and gives a patient relief from pain due to a damaged cornea. A corneal surgery or transplantation involves either removal of the entire thickness of the damaged cornea or just a portion of the damaged cornea. There are several methods of corneal surgery depending upon the damage caused to the cornea:

  • Penetrating keratoplasty (PK): In this procedure, the entire corneal thickness is transplanted using a special instrument. Corneal detachment doctors in Alwarpet cut through the damaged cornea and remove a button-sized portion of corneal tissue. Your doctor will then stitch the donor cornea into place.
  • Anterior lamellar keratoplasty (ALK): This procedure has two methods of corneal removal depending upon the depth of corneal damage. Superficial anterior lamellar keratoplasty (SALK) is used to remove only the front layers of your damaged cornea. Deep anterior lamellar keratoplasty (DALK) is used to treat deeply damaged corneas. The portion removed is then replaced by healthy tissue from a donor.
  • Endothelial keratoplasty (EK): This procedure is conducted to remove the damaged tissues from the back layers of the cornea which include the endothelium and a thin layer that protects the endothelium. Endothelial keratoplasty is of two types, descemet stripping endothelial keratoplasty (DSEK) and descemet membrane endothelial keratoplasty (DMEK). DMEK is the more commonly used procedure to treat a damaged cornea.  
  • Artificial cornea transplant (keratoprosthesis): In certain cases, a patient is not eligible for getting a donor cornea. Under such circumstances, corneal detachment doctors near you might use an artificial cornea (keratoprosthesis) to treat a damaged cornea.

Who qualifies for corneal surgery?

Corneal surgery is performed to treat several conditions such as:

  • If your cornea is thinning or it has torn
  • If your cornea is scarred because of an infection or injury
  • If you have corneal ulcers which cannot be treated with medicines

  • If you are suffering from a hereditary condition called Fuchs’ dystrophy

Why is corneal surgery conducted?

Corneal surgery is conducted by a corneal detachment specialist near you to restore vision because the cornea is largely associated with our vision. If the cornea is damaged or diseased, you might slowly lose vision. Moreover, corneal surgery is also performed to reduce pain because of corneal damage. Corneal damage can be identified by loss of vision, pain in the eyes, red eyes and sensitivity to light.   

What are the benefits of corneal surgery?

  • You can return to work within a week post surgery.
  • Eyesight gradually improves within a few weeks after corneal surgery.
  • Reduces eye pain from cornea damage.

What are the risks of corneal surgery?

Corneal surgery is mostly safe, but it poses risks such as:

  • Eye infection
  • High pressure in the eyeball (glaucoma)
  • Rejection of the donor cornea
  • Bleeding after corneal surgery
  • The stitches used to secure the donor cornea in place might create problems
  • Retinal detachment or retinal swelling after the corneal surgery


Corneal surgeries are mostly successful. The cases of cornea rejection can also be reversed in most cases if detected early. The risk of complications continues for some years after corneal surgery and therefore, you need to visit ophthalmology doctors in Chennai annually.




How long does it take to recover from corneal surgery?

It might take six to 12 weeks to see clearly. Your doctor will prescribe eye drops to help the eye heal faster to avoid donor tissue rejection.

Is corneal surgery painful?

Your ophthalmologist will use local or general anesthesia and therefore, you will feel no pain during corneal surgery.

Are you awake during corneal surgery?

In most cases, you are awake during corneal surgery. Your doctor will inject local anesthesia around your eyes which will block pain and prevent the movement of eyes during the procedure.
