Photorefractive keratectomy for the correction of residual refractive error with Intacs intrastromal corneal ring segments in place.

Purpose: To evaluate the efficacy and safety of photorefractive keratectomy (PRK) for residual refractive errors in patients who had previous insertion of intrastromal corneal ring segments (Intacs, Addition Technology, Inc.) for treatment of low myopia.

Setting: Shiley Eye Center, University of California San Diego, La Jolla, California, USA.

The effect of cyclosporine A (Restasis) on recovery of visual acuity following LASIK.

Purpose: To compare the recovery of uncorrected visual acuity (UCVA) following LASIK in patients treated with topical cyclosporine A 0.05% and patients treated with a standard postoperative regimen.

Methods: In this single-center, open-label, retrospective study, a standard refractive workup was performed in 45 patients (85 eyes) who underwent LASIK and did not have preexisting dry eye.

New surgical approaches to the management of keratoconus and post-LASIK ectasia.

Purpose: The objective of this study is to describe the authors' results with intrastromal corneal ring segments (Intacs) and a new variation of lamellar keratoplasty, termed intralamellar keratoplasty (ILK), for the treatment of keratoconus (KCN) and post-laser-assisted in situ keratomileusis (LASIK) ectasia.

Methods: A retrospective review of contact lens-intolerant KCN and post-LASIK ectasia cases that had surgery with either Intacs or ILK was performed. The end points were mean uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), spherical equivalent (SE), manifest and topographic cylinder, and restoration of contact lens tolerance.
