Safety and Efficacy of BroadBand Intense Pulsed Light Therapy for Dry Eye Disease with Meibomian Gland Dysfunction.

Background: BroadBand light intense pulsed light (BBL-IPL) therapy has shown to reduce hordeolum and blepharitis frequency. This study aims to evaluate the efficacy and safety of BBL-IPL therapy in patients with dry eye disease (DED) from meibomian gland dysfunction (MGD).

Methods: This is a retrospective, consecutive case series of 48 patients with DED from MGD who underwent BBL-IPL therapy from October 2016 to January 2019 at a single, outpatient clinic in Ontario, Canada.

Astigmatic Outcomes of Single, Non-Paired Intrastromal Limbal Relaxing Incisions During Femtosecond Laser-Assisted Cataract Surgery Based on a Custom Nomogram.

Purpose: To determine astigmatic changes of intrastromal limbal-relaxing incisions (LRIs) performed during femtosecond laser-assisted cataract surgery (FLACS).

Design: Retrospective case series.

Patients And Methods: Patients undergoing FLACS with adjunctive astigmatism management with intrastromal LRIs were included.

Comparison of Surgically Induced Astigmatism and Corneal Morphological Features Between Femtosecond Laser and Manual Clear Corneal Incisions.

Purpose: To assess corneal morphologic changes and surgically induced astigmatism (SIA) following clear corneal incisions (CCIs) created manually or with the Catalys femtosecond laser (Johnson & Johnson Vision, Santa Ana, CA).

Methods: In this retrospective cohort analysis, patients undergoing femtosecond laser-assisted cataract surgery (FLACS) or manual cataract surgery between June and September 2018 from a single surgical center in Toronto, Canada, were considered for inclusion. Postoperative corneal astigmatism values were compared to preoperative astigmatism indices to determine the SIA at the postoperative 3-month (POM3) mark using the Alpins vector method.

Refractive Laser-Assisted Cataract Surgery versus Conventional Manual Surgery: Comparing Efficacy and Safety in 3144 Eyes.

Purpose: To report on outcomes of the efficacy and safety in 1 of the largest series of eyes undergoing either conventional manual cataract surgery (MCS) or refractive femtosecond laser-assisted cataract surgery (ReLACS).

Design: Retrospective, consecutive, interventional comparative case series.

Methods: This study included 3144 consecutive eyes, of which 1580 were treated via MCS, and 1564 were treated via ReLACS at Uptown Surgical Centre in Vaughan, Ontario, Canada.

Outcome of cataract surgery in Nigeria: visual acuity, autorefraction, and optimal intraocular lens powers--results from the Nigeria national survey.

Objective: To describe presenting and corrected visual acuities after cataract surgery in a nationally representative sample of adults. Another objective was to describe refractive errors in operated eyes and to determine the optimal range of intraocular lens (IOL) powers for this population.

Design: Cross-sectional, population-based survey.

Pterygial derived fibroblasts express functionally active histamine and epidermal growth factor receptors.

Pterygia are characterised by a fleshy outgrowth of altered conjunctival tissue over the cornea and are most common in tropical regions. Pterygial fibroblasts are characteristically distinct from normal conjunctival fibroblasts, and therefore the aim of this study was to determine the presence and functional significance of histamine and epidermal growth factor (EGF) receptors in these cells. Pterygial specimens were cultured in vitro and cellular outgrowths were phenotypically characterised as fibroblasts using vimentin and cytokeratin staining.

Use of mitomycin C in the treatment of corneal conjunctival intraepithelial neoplasia.

Purpose: To evaluate the efficacy of topical mitomycin C as a treatment of corneal conjunctival intraepithelial neoplasia.

Methods: An open prospective analysis of 20 cases of corneal conjunctival intraepithelial neoplasia with recurrent disease (17 patients) or refusing surgery (three patients) were treated with topical mitomycin C. Treatment was with mitomycin C eye drops, either 0.
