Corneal Transplantation
Cornea transplantation is the replacement of the diseased portion of cornea (black portion of eyeball) with donated eye. It can be a full-thickness replacement (Penetrating keratoplasty or PK). We can also replace the innermost layer (endothelium) alone (Descemet stripping endothelial keratoplasty or DSEK & Descemet membrane endothelial keratoplasty or DMEK) without need for sutures and with a reduced risk of allograft rejection. Defects in the outer layers can be removed – superficial ones with laser (photo-therapeutic keratectomy or PTK) and deeper ones with Deep anterior lamellar keratoplasty or DALK.
Contact lenses
Soft lenses are now available as disposable lenses with low risk of deposit buildup and complications. High oxygen supply lenses (silicone hydrogel lenses) maintain corneal health and provide extra safety even with extended wear. Toric contact lenses can correct astigmatism for sharp vision. We also deal with multifocal lenses, which help people above 40 to see far and near. Special lenses are available for irregular corneas.

Collagen Cross-Linking
It’s a corneal strengthening procedure to halt the progress of the disease. It is safe and effective for progressive keratoconus. Many patients end up with better spectacle corrected vision following the treatment. It’s best done before the corneal thickness goes below 450 um. It can be done for children and adults.
Intra-corneal rings
These acrylic segments flatten the conical (diseased) portion of the cornea and improve unaided and spectacle corrected visual acuity. It is a reversible procedure.
Implantable contact lens (ICL)
In selected cases, ICL can provide significant improvement in unaided vision
Laser kerato-refractive surgery
While LASIK is typically contraindicated in patients with keratoconus, newer treatment modalities have made it possible to use laser for correcting refractive errors in these patients. Surface ablation (Trans-epithelial PRK) combined with collagen cross-linking is being used for selected patients with keratoconus.
Keratoplasty
Both full-thickness (PK) and partial-thickness (DALK) keratoplasty procedures have high success rates in advanced cases of keratoconus. Also, the risk of graft rejection is the least in keratoconus.
Pterygium
A firbro-vascular growth into the black portion of the eye (cornea) from the white part of the eye ball. Recurrence was a common problem with earlier surgical procedures (excision with bare sclera). Modern procedures {Limbal auto-graft (CLAG) & Stitch-less (Fibrin glue)} made permanent cure possible.
