Prospective evaluation of intraocular lens calculation after myopic refractive surgery.

Purpose: To evaluate outcome after refractive surgery in cataract patients for whom intraocular lens (IOL) selection was based on the use of a myopic regression formula.

Methods: This prospective case series included 20 eyes of 14 patients who had previous uncomplicated myopic refractive surgery, followed by uncomplicated cataract extraction with IOL implantation. Calculation of IOL was based on flattest keratometry readings, spherical equivalent refraction before refractive surgery, and an adjustment factor derived from the regression formula: -(0.

Effect of punctal plugs in patients with low refractive errors considering refractive surgery.

Purpose: To study the effect of punctal plug placement in patients undergoing refractive surgery for correction of poor vision.

Methods: A retrospective study was performed of 12 patients (21 eyes) who presented for initial refractive surgery or retreatment after LASIK or photorefractive keratectomy to improve visual acuity. Uncorrected visual acuity (UCVA) was documented in each eye.

Intraocular lens calculations after hyperopic refractive surgery.

Purpose: To evaluate the effect of hyperopic refractive surgery on intraocular lens (IOL) power calculation, compare published methods of IOL power calculation after refractive surgery, evaluate the effect of prerefractive surgery refractive error on IOL deviation, and introduce a new alternative formula for IOL calculation in patients who have had refractive surgery for hyperopia.

Design: Retrospective noncomparative case series.

Participants: Twenty eyes from 13 patients who had undergone cataract surgery after previous hyperopic refractive surgery.

Optic pit maculopathy after laser-assisted in situ keratomileusis.

Case Report: Optic disc pit is an embryological malformation of the optic nerve that occurs in less than one in 10,000 people. It is 10%-15% bilateral, and 25% to 70% of patients develop a neurosensory macular detachment within the 2nd to 4th decade.

Comments: We report a case of unilateral optic disc pit maculopathy 2 months after laser-assisted in situ keratomileusis (LASIK) revision.

Transverse keratotomy followed by LASIK for the treatment of naturally occurring astigmatism.

Purpose: To evaluate the efficacy of transverse keratotomy followed by LASIK for patients with high amounts of naturally occurring astigmatism.

Methods: Thirteen eyes with naturally occurring astigmatism ranging from -3.75 to -6.

Effect of artificial tears on visual acuity.

Purpose: To study the effect of commonly used preservative free artificial tear, carboxymethylcellulose (CMC) 0.5% (Refresh Plus, Allergan, Irvine, California) on visual acuity in symptomatic dry eye (SDE) and asymptomatic dry eye (ADE) patients.

Design: Nonrandomized prospective clinical trial.

Traumatic flap dislocation 4 years after laser in situ keratomileusis.

We present a case of late traumatic flap dislocation 47 months after laser in situ keratomileusis (LASIK). This is the latest reported case of traumatic LASIK flap dislocation to date. The patient was examined 5 days after being struck in the face and found to have a flap dislocation.

Intraocular lens calculations after refractive surgery.

Purpose: To evaluate the effect of refractive surgery on intraocular lens (IOL) power calculation, compare methods of IOL power calculation after refractive surgery, evaluate the effect of pre-refractive surgery refractive error on IOL deviation, review the literature on determining IOL power after refractive surgery, and introduce a formula for IOL calculation for use after refractive surgery for myopia.

Setting: Laser & Corneal Surgery Associates and Center for Ocular Tear Film Disorders, New York, New York, USA.

Methods: This retrospective noncomparative case series comprised 21 patients who had uneventful cataract extraction and IOL implantation after previous uneventful myopic refractive surgery.

Advanced epithelial ingrowth 6 months after laser in situ keratomileusis.

Epithelial ingrowth is a common complication of laser in situ keratomileusis (LASIK). The cause is thought to be postoperative invasion of surface epithelial cells under the flap. We present a case of advanced epithelial cystic ingrowth that caused a profound reduction in visual acuity 6 months after a second LASIK enhancement.

To lift or recut: changing trends in LASIK enhancement.

Purpose: To report serious complications caused by recutting laser in situ keratomileusis (LASIK) flaps for enhancement and reconsider the current preferred method of LASIK enhancement.

Setting: Multiple surgeon practices.

Methods: This retrospective noncomparative nonconsecutive case series comprised LASIK patients in the private practices of 9 experienced refractive surgeons and those reported in a survey of refractive surgeons.

Infectious keratitis after photorefractive keratectomy.

Purpose: To elucidate risk factors, microbial culture results, and visual outcomes for infectious keratitis after photorefractive keratectomy (PRK).

Design: Multicenter, retrospective chart review, case report, and literature review.

Methods: The records of 12 patients with infectious keratitis after PRK were reviewed.
