Corneal Haze Secondary to Corneal Collagen Cross-linking in Keratoconus Patients: Treatment and Outcomes.

Purpose: The purpose of this study was to evaluate the outcome of patients presenting with mild-to-moderate corneal haze after undergoing corneal collagen cross-linking (CXL) for keratoconus (KCN) and their response to a proposed standardized topical steroid-based treatment.

Methods: This study included 19 eyes of 14 patients presenting with corneal haze after undergoing CXL for KCN. Corrected distance visual acuity, corneal thickness and Kmax values by Pentacam Scheimpflug tomography, as well as subjective corneal haze changes were evaluated before and after a topical steroid- and cyclosporine-based treatment.

Cystoid Macular Edema 18 Years after Anterior Chamber Phakic Intraocular Lens Implantation.

We report a case of a 54-year-old female patient who underwent PAC-IOL implantation 18 years prior to presentation. The patient had a best corrected visual acuity (BCVA) 20/20 in the right eye (OD) postoperatively with normal eye exam on routine follow-up since then. The patient presented for acute onset decreased visual acuity in the right eye.

Hydrophilic Lens Opacification after Intravitreal Anti-VEGF Injections: A Case Series.

Our objective in this retrospective case series was to report 4 cases of hydrophilic intraocular lens (IOL) opacifications after repeated intravitreal bevacizumab injections. This is a retrospective analysis of all the cases of IOL opacifications presenting to a tertiary referral ophthalmic center in Beirut between January 2013 and January 2019. Four cases were included in the study, of which one was treated for vitreal hemorrhage, the other for macular edema secondary to wet age-related macular edema, and the rest for macular edema secondary to diabetic retinopathy.

Long-term follow up of intracorneal ring segment implantation in 932 keratoconus eyes.

Purpose: To evaluate the progression of keratoconus in 932 eyes of 659 patients through visual, refractive and topographic data after intracorneal ring segment (ICRS) implantation.

Methods: Retrospective review of 659 patients who underwent ICRS (Intacs®) implantation for keratoconus between September 1997 and November 2017. Demographics, preoperative and postoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA) in LogMAR, corneal topography parameters (thinnest pachymetry, Kmax), central corneal pachymetry and total follow-up time were evaluated.

Allogenic corneal tissue transplantation in substitution for extruded intracorneal rings: A case series.

We describe a case series of four eyes of four keratoconus patients with extruded intracorneal ring segments (ICRS) in whom donor corneal tissue was used to substitute for the extruded ICRS in an attempt to preserve its effect. In all patients, the extruded intracorneal ring was removed through the exposed area. Donor corneal tissue (tailored to the size and shape of the ICRS) was inserted into the empty ICRS tunnel and fixed in place using 10-0 nylon sutures.
