There are long-lasting benefits to be had from undergoing a corneal graft operation to cure defective vision, one source has noted.
Ophthalmic professional Dr Anthony Felipe said that people who have undergone penetrating keratoplasty (PK) for conditions such as keratoconus have both high graft survival rates and good visual outcomes up to 20 years after the operation, OSN Supersite reported.
The expert added that detection and treatment of complications are both crucial to graft survival and visual outcome, though in many cases topical steroids can be used as a treatment.
"Overall, 81 per cent of eyes had Snellen best corrected visual acuity of 20/20 to 20/40 with rigid gas-permeable contact lenses or glasses. Among eyes that underwent PK for keratoconus, 73.2 per cent had BCVA of 20/40 or better," the website stated.
Meanwhile, a recent post on Live PR noted that scleral lenses, which are large-diameter, gas-permeable lenses that cover a greater part of the eye than normal lenses, are becoming more popular with people who have irregularly-shaped corneas.
