Disposable contact lenses in penetrating keratoplasty
1Cornea Service, Guru Nanak Eye Centre and Assoc., Maulana Azad Medical College, New Delhi, Pin, India.
Purpose:
To evaluate the therapeutic efficacy of disposable contact lenses in management of complications after keratoplasty.
Methods:
Twenty-eight patients with various post keratoplasty complications were fit with disposable contact lenses (45% Vifilcon A and 55% water content). Indications for lens use included persistent epithelial defects, wound leak, graft edema, dry eye and protection of normal corneal epithelium.
Results:
Success was obtained with the therapeutic use of disposable lenses in 20 of the 28 cases. The best results were seen in maintenance and restoration of healthy ocular surface and small wound leaks. Stromal graft edema with no epithelial involvement was the major area of therapeutic failure.
Conclusions:
Disposable contact lenses are an attractive low cost option in the management of complications after keratoplasty. They are particularly useful in maintaining a healthy ocular surface, providing symptomatic relief and avoiding resurgery in patients with small wound leaks.
