Descemet stripping automated endothelial keratoplasty using donor corneas with previous laser in situ keratomileusis or photorefractive keratectomy: a case series and donor cap histopathology.

Purpose: To report outcomes in Descemet stripping automated endothelial keratoplasty (DSAEK) using donor tissue from eyes that have had previous refractive surgery and to report histopathology of the donor free cap.

Methods: Retrospective case series. Preoperative and postoperative data were collected on each patient, and donor information was collected.

Laser in situ keratomileusis flap complications using mechanical microkeratome versus femtosecond laser: retrospective comparison.

Purpose: To compare the incidence of flap complications after creation of laser in situ keratomileusis (LASIK) flaps using a zero-compression microkeratome or a femtosecond laser.

Setting: John A. Moran Eye Center, Department of Ophthalmology, University of Utah, Salt Lake City, Utah, USA.

Prospective, contralateral comparison of 120-μm and 90-μm LASIK flaps using the IntraLase FS60 femtosecond laser.

Purpose: To compare differences in visual acuity, contrast sensitivity, higher order ocular aberrations, quality of life, and patient-reported outcomes at 3 and 6 months postoperatively in eyes with stable myopia undergoing thin-flap (intended flap thicknesses of 120 or 90 μm) LASIK using the VISX Star S4 CustomVue excimer laser (VISX Inc), with flaps created by the IntraLase FS60 femtosecond laser (Abbott Medical Optics).

Methods: In this prospective study, thin-flap LASIK was performed contralaterally on 94 eyes: 47 eyes with 120-μm intended flap thickness and 47 eyes with 90-μm intended flap thickness. Primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), contrast sensitivity, and higher order aberrations.

Visual outcomes after wavefront-guided photorefractive keratectomy and wavefront-guided laser in situ keratomileusis: Prospective comparison.

Purpose: To compare visual outcomes between wavefront-guided photorefractive keratectomy (PRK) and wavefront-guided laser in situ keratomileusis (LASIK).

Setting: Academic center, Salt Lake City, Utah, USA.

Methods: In this randomized prospective study, myopic eyes were treated with wavefront-guided PRK and or wavefront-guided LASIK using a Visx Star S4 CustomVue platform with iris registration.

Iris-fixated phakic intraocular lens implantation for correction of high myopia in microspherophakia.

We report the refractive correction of high myopia in a 23-year-old patient with idiopathic microspherophakia using iris-fixated phakic intraocular lenses (pIOLs) (Verisyse/Artisan). Four years after bilateral implantation, the uncorrected distance visual acuity was 20/25 with a correction of 20/20(-1) in both eyes. No intraoperative or postoperative complications occurred.

Cataract surgery following phakic intraocular lens implantation.

Purpose Of Review: To review the most recent literature regarding the incidence and pathophysiology of phakic intraocular lens (pIOL) associated cataracts, surgical issues and outcomes of combined pIOL explantation/cataract surgery, and the prevention of cataract formation secondary to pIOLs.

Recent Findings: The overall rate of cataracts secondary to pIOLs is low, but a disproportionate number is associated with posterior chamber pIOLs. All combination pIOL explantation/cataract surgeries resulted in the successful implantation of a posterior chamber intraocular lens in the capsular bag.
