Pilot Safety Study of a Microfabricated Device for Anterior Stromal Puncture to Treat Corneal Epithelial Disease in the Optical Axis.

Purpose: Anterior stromal puncture is an inexpensive and widely used technique at the slit lamp to treat recurrent corneal erosions (RCE), common sequelae of corneal abrasions, trauma, and epithelial basement membrane dystrophies (EBMDs). The purpose of this study was to determine safety of a novel anterior stromal micropuncture device (termed a "plexitome") for use in the optical axis of the cornea.

Methods: We performed an IRB-approved clinical pilot study on 45 patients with diverse corneal pathologies to determine the safety of the plexitome device and examined corneal healing responses clinically for a minimum of 30 days after treatment.

Multifocal and Accommodating Intraocular Lenses for the Treatment of Presbyopia: A Report by the American Academy of Ophthalmology.

Purpose: To review the published literature assessing the efficacy and safety of presbyopia-correcting intraocular lenses (IOLs) for the treatment of presbyopia after cataract removal.

Methods: Literature searches were undertaken in January 2018 and September 2020 in the PubMed, Medline, and Cochrane Library databases. This yielded 761 articles, of which 34 met the criteria for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist.

Risk for microbial keratitis: Comparative metaanalysis of contact lens wearers and post-laser in situ keratomileusis patients.

Purpose: To compare the risk for microbial keratitis in contact lens wearers stratified by wear schedule with the risk after laser in situ keratomileusis (LASIK).

Setting: Hamilton Eye Institute and Department of Ophthalmology, University of Tennessee Health Science Center, Memphis, Tennessee, USA.

Design: Comparative metaanalysis and literature review.

Continuous Curvilinear Capsulorhexis Performed With the VERUS Ophthalmic Caliper.

Purpose: To compare size, circularity, and centration outcomes of continuous curvilinear capsulorhexis (CCC) performed with or without assistance from the VERUS ophthalmic caliper (Mile High Ophthalmics, Denver, CO).

Methods: This was a multicenter retrospective consecutive case controlled series review.

Results: Data from 40 consecutive cases using the VERUS device for CCC were compared to 40 consecutive cases with standard manual CCC.

Localized opacification of hydrophilic acrylic intraocular lenses after procedures using intracameral injection of air or gas.

Purpose: To describe clinical and laboratory findings in a series of cases of intraocular lens (IOL) opacification after procedures involving intracameral injections of air or gas.

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

Descemet-stripping automated endothelial keratoplasty donor tissue preparation using the double-pass microkeratome technique.

Purpose: To compare human donor corneal lenticule thickness, endothelial cell viability, area of cell damage, and cell counts between corneal tissue prepared with a double-pass microkeratome cut versus the standard single-pass microkeratome cut.

Setting: University of Colorado Teaching Hospital, Aurora, Colorado, USA.

Design: Experimental study.

Emergency lateral canthotomy and cantholysis: a simple procedure to preserve vision from sight threatening orbital hemorrhage.

Retrobulbar hemorrhage is an uncommon, but potentially devastating complication associated with facial trauma. It can rapidly fill the orbit and cause an "orbital compartment syndrome" that subsequently cuts off perfusion to vital ocular structures, leading to permanent visual loss. Treatment must be initiated within a limited time in order to prevent these effects; however, specialty consultation is not always available in remote field environments.

Glistenings in the single-piece, hydrophobic, acrylic intraocular lenses.

Purpose: To study glistenings in single-piece AcrySof (models SA60 and SN60; Alcon, Fort Worth, Texas, USA) intraocular lenses (IOLs).

Design: Observational, longitudinal study.

Methods: Consecutive patients with the SA60 were examined at 12, 24, and 36 months after surgery; those with the SN60 were examined 12 months after surgery.

Phacoemulsification tip vacuum pressure: Comparison of 4 devices.

Purpose: To determine the vacuum pressure generated by 4 phacoemulsification devices measured at the phacoemulsification tip.

Setting: University ophthalmology department.

Methods: The effective vacuum pressures generated by the Sovereign (AMO), Millennium (Bausch & Lomb), Legacy AdvanTec (Alcon Laboratories), and Infiniti (Alcon Laboratories) phacoemulsification machines were measured with a device that isolated the phacoemulsification tip in a chamber connected to a pressure gauge.

Thermal inertia associated with ultrapulse technology in phacoemulsification.

Purpose: To determine whether very short pulses of ultrasound (5 to 6 milliseconds) have less heat propagation in biological tissue (thermal inertia) than traditional pulses (50 milliseconds).

Setting: Department of Ophthalmology and Visual Sciences, University of Utah Health Sciences Center, Salt Lake City, Utah.

Methods: Thermal testing was done in balanced salt solution (BSS) and in eye-bank eyes.
