Evaluation of biometry and corneal astigmatism in cataract surgery patients in Northern United Arab Emirates.

Purpose: To analyze biometric parameters and patterns of corneal astigmatism in cataract surgery patients using optical low-coherence interferometry in Northern United Arab Emirates (UAE).

Methods: Axial length (AL), anterior chamber depth (ACD), horizontal corneal diameter (white to white, WTW) and flat and steep keratometry (K1 and K2, respectively) were optically measured using optical low-coherence interferometry (Aladdin). Ocular datasets acquired between 2015 and 2018 were collected and analyzed.

Long-term outcome and prognostic factor analysis for keratolimbal allografts.

Purpose: To evaluate the long-term results of keratolimbal allograft (KLAL) and elucidate the prognostic factors of KLAL survival.

Methods: Twenty-four eyes of 22 patients underwent KLAL one or more times, and were followed up more than 1 year postoperatively. Their medical records were reviewed.

Aqueous humor concentration of bevacizumab after subconjunctival injection in rabbit.

Purpose: To investigate whether bevacizumab may be delivered into the anterior chamber after subconjunctival administration and its pharmacokinetics in aqueous humor.

Methods: The right eye of 33 rabbits received subconjunctival injection of 2.5 mg of subconjunctival bevacizumab.

The effect of diffuse lamellar keratitis on visual acuity and contrast sensitivity following LASIK.

Purpose: To evaluate visual outcome and the changes of contrast sensitivity (CS) after diffuse lamellar keratitis (DLK).

Methods: Using retrospective chart review, 48 eyes of 25 patients who underwent laser in situ keratomileusis (LASIK) with Visx S4 (VISX Inc., Santa Clara, CA) and M2 (Moria, France) and who were followed for at least six months were included.

Using red-free monochromatic conversions of nonmydriatic digital fundus images.

Purpose: To compare three types of digital images for assessment of retinal nerve fiber layer (RNFL) defects: red-free RNFL images, color nonmydriatic images, and digitally converted nonmydriatic red-free fundus images.

Design: Diagnostic test comparison.

Methods: Ninety-five image sets of three type images were evaluated.

The long-term safety of donor eye for 180 degrees limbal transplantation.

Background: Little information is currently available on the long-term safety of eyes following limbal tissue donation. We have therefore evaluated long-term refractive changes, corneal surface stability, and visual outcome following limbal tissue donation of 180 degrees with permanent amniotic membrane transplantation (AMT).

Methods: Four healthy eyes of four patients underwent limbal keratectomy involving half of the limbal circumference (half limbal) for the purpose of limbal donation with permanent AMT.

Intraocular lens power calculation in high myopic eyes with previous radial keratotomy.

Purpose: To determine an accurate method of intraocular lens (IOL) power calculation in highly myopic eyes with previous radial keratotomy (RK).

Methods: Five eyes that had undergone RK with preoperative myopia >-14.0 diopters (D) were studied retrospectively.

The effects of external subretinal fluid drainage on secondary glaucoma in Coats' disease.

Purpose: We sought to investigate the effect of external subretinal fluid drainage (SRFD) on secondary or impending secondary glaucoma caused by bullous exudative retinal detachment for saving eyes with Coats' disease.

Methods: By retrospective chart review, we collected the treatment results of 56 patients younger than 15 years of age with Coats' disease. External SRFD was performed when exudative retinal detachment became bullous enough to cause anterior displacement of the lens-iris diaphragm or when secondary angle-closure glaucoma occurred.
