Use of Cryopreserved Amniotic Membrane During Pterygium Excision: Health Economic Analysis.

Purpose: To determine the health economic opportunity cost or gain associated with performing pterygium excision surgery using the TissueTuck technique with cryopreserved amniotic membrane (AM) instead of conjunctival autograft (CAU).

Methods: We performed a literature review to determine the average surgical duration of pterygium surgery using CAU with fibrin glue or sutures to calculate the average time saved with the TissueTuck technique. Such time savings was then used to determine the opportunity revenue gain per national average Medicare reimbursement if adjusted to the average surgical duration of cataract surgery.

Outcomes of the TissueTuck Surgical Technique for Recurrent Pterygium.

Purpose: The objective of this study was to evaluate the clinical outcomes of the TissueTuck technique in the treatment of eyes with recurrent pterygium.

Methods: A retrospective review was performed on patients with recurrent pterygium who underwent surgical excision, followed by the application of cryopreserved amniotic membrane, using the TissueTuck technique between January 2012 and May 2019. Only patients with at least 3 months of follow-up were included for analysis.

Cryopreserved Amniotic Membrane Using the TissueTuck Technique: A Sutureless Approach for Pterygium Surgery.

Purpose: The purpose of this study was to evaluate the clinical outcomes of the TissueTuck technique in the management of pterygium.

Methods: This was a single-center, retrospective review of patients with primary or recurrent pterygium that underwent surgical excision followed by application of cryopreserved amniotic membrane (AM) using the TissueTuck technique. All patients underwent surgery between January 2012 and May 2019.

Intense pulsed light improves signs and symptoms of dry eye disease due to meibomian gland dysfunction: A randomized controlled study.

Purpose: To compare the safety and efficacy of intense pulsed light (IPL) followed by meibomian gland expression (MGX), against monotherapy of MGX.

Methods: Patients with moderate to severe meibomian gland dysfunction (MGD) were 1:1 randomized to 4 sessions of intense pulse light + MGX at 2-week intervals, or 4 sessions of Sham + MGX at 2-week intervals. Both patients and examiners were blinded to the allocation.

Crystalline lens endocapsular fragmentation using an elastic loop filament.

Purpose: To describe a novel mechanical endocapsular fragmentation technique of the crystalline lens during cataract surgery using a loop elastic-thin filament.

Methods: An alternative method to mechanically fragment the crystalline lens utilizing a nitinol loop is described. This device achieves lens sectioning in multiple pieces, decreasing ultrasonic energy expenditure during cataract surgery.

Comparison of prediction error: labeled versus unlabeled intraocular lens manufacturing tolerance.

Purpose: To compare the prediction error between intraocular lenses (IOLs) available in 0.25 diopter (D) increments with a labeled manufacturing tolerance and IOLs available in 0.50 D increments without a labeled manufacturing tolerance.

Use of a microvascular clip for iris fixation of an intraocular lens: a laboratory model.

Here we present a potential novel surgical technique consisting of fixation of a posterior-chamber intraocular lens to the iris that may be used in the treatment of aphakia or the management of intraocular lens complications when capsular support has been compromised. The technique was performed in a laboratory model using cadaveric human eyes. A commercially available neurovascular clip was used to securely fasten the intraocular lens to the iris with minimal trauma.

Secondary angle closure caused by air migrating behind the pupil in descemet stripping endothelial keratoplasty.

Purpose: To report secondary angle closure caused by air migrating behind the pupil in the context of intraocular pressure (IOP) elevation in the early postoperative period after Descemet stripping endothelial keratoplasty (DSEK).

Methods: A retrospective case series was conducted on 100 consecutive DSEK cases from 90 patients undergoing DSEK because of corneal disease from Fuchs corneal dystrophy, pseudophakic bullous keratopathy, aphakic bullous keratopathy, and iridocorneal endothelial syndrome. Preoperative and postoperative slit-lamp examinations and IOP measurements were ascertained for all 100 eyes.

Presoaking donor corneas reduces graft detachment rates in descemet stripping endothelial keratoplasty.

Purpose: To present a novel method of reducing rates of graft detachment, the most common postoperative complication of Descemet stripping endothelial keratoplasty (DSEK).

Design: Retrospective, interventional case series.

Methods: Eighty-three consecutive patients undergoing DSEK for endothelial dystrophy were studied.
