#6
Somya Chowdhary, Ken K Nischal
We describe a technique for pediatric traumatic cataract management in cases in which part of the anterior capsule has been ruptured. The technique requires creating a 2-incision push-pull capsulorhexis in the intact anterior capsule. The capsulorhexis is made in a manner that converts the edge of the ruptured anterior capsule into a band of capsule that holds the intraocular lens (IOL) in the bag, reducing the incidence of early, intermediate, or late postoperative lens-iris capture. It also reduces the chances of IOL displacement...

PURPOSE: To examine the relationship between corneal higher-order aberrations (HOAs), scatter, and residual refraction with visual symptoms and visual acuity after small-incision lenticule extraction (SMILE) for myopia and astigmatism. SETTING: University Eye Clinic, Aarhus, Denmark. DESIGN: Prospective case series. METHODS: Eyes had small-incision lenticule extraction for myopia or myopic astigmatism. Examinations were performed preoperatively and 1 day, 7 days, 1 month, and 3 months postoperatively and included subjective refraction, Pentacam HR measurements, scatter measurements (objective scatter index [OSI]), and questionnaires on visual quality and symptoms...

Shikha Gupta, Harathy Selvan, Viney Gupta
We describe a modified sewing machine technique that is ab interno and minimally invasive. The single-suture, single-knot endocyclopexy (internal suture fixation) is performed to correct cyclodialysis. This inside-out technique is an alternative to existing standard cleft repair procedures, such as external direct/indirect cyclopexy and endocyclotamponade (internal mechanical tamponade using extraneous agents). Results in 1 case indicate that the modified technique can be used as a primary procedure and in eyes in which previous cyclopexy failed...

Thomas John, Sean Tighe, Omar Hashem, Hosam Sheha
We describe 4-point scleral fixation of a posterior chamber intraocular lens (PC IOL) using 8-0 polypropylene (Prolene) sutures, without the handshake technique. First, 4 sclerotomy sites are marked 2.5 mm from the limbus, and 2 scleral grooves are created in between. Two sets of 8-0 polypropylene sutures are then passed through the IOL haptics. The PC IOL is inserted behind the iris, and the sutures are pulled ab interno and tightened for optimum IOL centration. The sutures and exposed knots are imbedded within the scleral groove and sealed with fibrin glue...

REVIEW
Hidenaga Kobashi, Shi Song Rong, Joseph B Ciolino
This review compared the clinical results of transepithelial corneal crosslinking (CXL) to epithelium-off (epi-off) CXL in progressive corneal ectasia using a metaanalysis. The Cochrane databases and Medline were searched for randomized controlled trials (RCTs). Seven RCTs involving 505 eyes that met the eligibility criteria were identified. The epi-off CXL group showed significantly better outcomes in postoperative changes in maximum keratometry (K) during 1-year observation periods. Transepithelial CXL resulted in significantly greater post-treatment central corneal thickness and best spectacle-corrected visual acuity (BSCVA)...

John C Hart, Michael Tanner, David M Rooney
We describe 2 cases of posterior capsule rupture caused by Alcon reusable silicone irrigation/aspiration (I/A) tips. Scanning electron microscopy and reflected light microscopy of these tips revealed burring of the inner metallic shafts and tears in the silicone sleeves. A review of surgical video revealed that posterior capsule ruptures caused by the I/A tips occurred when the posterior capsule was aspirated either through the aspiration port or through a tear in the silicone sleeve. Contact of the posterior capsule with the sharp metallic burrs on the inner metal tube can result in posterior capsule rupture...
