Orbscan II-assisted intraocular lens power calculation for cataract surgery following myopic laser in situ keratomileusis (an American Ophthalmological Society thesis).

Purpose: This study tests the hypothesis that the keratometric value derived from Orbscan II mean power maps, when used in an intraocular lens (IOL) calculation formula, at a specific measurement zone, will accurately determine the power of an IOL for planned cataract surgery in patients who have undergone prior myopic laser-assisted in situ keratomileusis (LASIK).

Methods: This is a two-part study conducted in a referral practice. Experiment 1 is a prospective study of 59 eyes of 30 patients undergoing LASIK.

Possible role of the vitamin E solubilizer in topical diclofenac on matrix metalloproteinase expression in corneal melting: an analysis of postoperative keratolysis.

Objective: To analyze tissue matrix metalloproteinase (MMP) expression in three patients who developed postoperative corneal melts after treatment with topical diclofenac sodium 0.1% (Falcon; Fort Worth, TX) ophthalmic solution.

Design: Retrospective noncomparative interventional case series with tissue analysis.

Mycobacterium keratitis after laser in situ keratomileusis.

Purpose: The authors report two cases of Mycobacterium keratitis following LASIK.

Methods: The case reports are based on a retrospective review of clinical history and associated findings.

Results: Two patients developed infectious keratitis after undergoing laser in situ keratomileusis (LASIK).

Persistent Torulopsis magnoliae endophthalmitis following cataract extraction.

Postoperative fungal endophthalmitis typically manifests as an indolent uveitis, weeks to months after surgery. In our patient, Torulopsis magnoliae endophthalmitis appeared as an acute, purulent postoperative endophthalmitis on the third day following extracapsular cataract extraction with implantation of a posterior chamber intraocular lens (IOL). The patient required three separate vitrectomy operations with instillation of intravitreal Amphotericin B; the last operation also included complete removal of the posterior capsule and IOL.

Management of corneal astigmatism after cataract surgery.

High degrees of surgically induced astigmatism following cataract surgery may limit the desired visual rehabilitation. The induced astigmatism is a reflection of the cataract incision, its closure, and subsequent wound healing. Excessively tight sutures induce central corneal steepening.
