Purpose: Corneal collagen crosslinking (CXL) with ultraviolet-A energy plus riboflavin has become a ubiquitous treatment in early keratoconus, although its long-term safety is unknown. We describe severe sequelae in a CXL-treated patient after he underwent a standard deep anterior lamellar keratoplasty procedure.
Methods: In April 2009, a healthy 49-year-old male patient (R.
Purpose: To report the use of circular keratotomy in eyes with stage I and II keratoconus to reduce astigmatism.
Methods: A retrospective analysis was performed of all eyes operated from 1993 to 2006 by one surgeon using circular keratotomy for stage I and II keratoconus. Results were evaluated for reduction of corneal astigmatism, refractive stability, and change in best spectacle-corrected visual acuity (BSCVA).

Purpose: To report the clinical outcomes of an intrastromal corneal ring (ISCR) used in penetrating keratoplasty (PKP) that was designed to decrease postoperative corneal astigmatism, stabilize refraction, accelerate healing, and possibly reduce immune reactions.
Materials And Methods: An 8 mm cobalt-titanium-molybdenum alloy ring was sutured into the PKP wounds. A prospective study compared the outcomes of PKP in 179 consecutive cases with a ring (Group 1) and 101 consecutive patients without a ring (Group 2).
