Retention rates were excellent, and best-corrected visual acuities improved in the vast majority of patients. Complications can occur and require frequent follow-up to monitor and treat glaucoma progression, endophthalmitis, and inflammation. Patient compliance is of paramount importance. Despite the potential complications, the Boston KPro provides visual improvement in patients with an otherwise poor prognosis.

Ab externo scleral fixation of IOLs with Gore-Tex suture was well tolerated in all cases. No suture-related complications were encountered. This procedure led to improvement in visual acuity and was not associated with significant intraoperative or postoperative complications.

Cataract surgery can improve BCVA in all severities of keratoconus without significant corneal change. IOL calculation is more predictable in mild keratoconus than in moderate and severe disease.

In this review, we analyze the trends in corneal transplantation over the past 25 years in the United States. The most dramatic change was the progressive sharp increase in the number of corneal transplants performed during the 1980s, corresponding with the rise of pseudophakic bullous keratopathy (PBK) as the leading indication for keratoplasty. More recently, there has been a steady annual decline in total keratoplasties for more than a decade, corresponding with a decline in the cases performed for PBK, which still accounts for the highest percentage of cases done. Regrafts have been an increasingly important indication for keratoplasty, as older grafts fail. Keratoconus, Fuchs dystrophy, and other inherited diseases have remained consistent indications for keratoplasty during the last quarter century.
