Twenty-one months after successful small-aperture corneal inlay (Kamra) implantation simultaneous with myopic laser in situ keratomileusis, a patient presented with a superior rhegmatogenous macula-involving retinal detachment. Successful pars plana vitrectomy, transscleral cryotherapy, and gas tamponade were performed with the inlay in situ. Three months later, uneventful phacoemulsification and posterior chamber intraocular lens implantation were performed, also with the inlay in situ, for a visually significant cataract...

REVIEW
David J Hernstadt, Rahat Husain
Cataract surgery is a common procedure, and cystoid macular edema (CME) is a sight-threatening complication. Prostaglandin analogues are the first-line therapy for glaucoma, but their effect on the risk for CME after phacoemulsification is unknown. A systematic search of Medline and PubMed was performed to determine the effect of the use of prostaglandin analogues (PGA) on the development of CME after cataract surgery. A total of 412 articles were identified. Thirteen articles met inclusion criteria and were analyzed using Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) criteria...

Tamar Pedut Kloizman, Raneen Shehadeh Mashour
Intraoperative floppy iris syndrome (IFIS) was first described by Chang and Campbell in 2005. The characteristics of this syndrome include: 1. Floppy iris that billows in reaction to intraocular fluid currents during standard phacoemulsification procedure; 2. Flaccid iris stroma that tends to prolapse through well-constructed surgical incisions; 3. Insufficient pupillary mydriasis despite proper pharmacologic preparation and progressive pupillary constriction during the operation. Surgical procedures with IFIS have since been noted to have an exceptionally high rate of complications, some of which can be vision threatening...

OBJECTIVE: To evaluate the changes in the intraocular pressure (IOP) following an intentionally induced posterior lens capsule rupture (PLCR) during phacoemulsification in enucleated canine eyes. Furthermore, to compare the IOPs between different stages of phacoemulsification for two different bottle heights (BH). PROCEDURES: Coaxial phacoemulsification was performed using a venturi-based machine at a 60 or 90 cm BH.

Objective: To investigate the visual impact and influence factors of sub-Tenon's anesthesia in retinal detachment patients during pars plana vitrectomy (PPV) or combined phacoemulsification and PPV surgery. Methods: In this prospective case series study, 104 consecutive patients who underwent PPV or combined phacoemulsification and PPV under sub-Tenon's anesthesia between October 2012 and December 2013 were enrolled. Intraoperatively, the patients were asked whether they could see the light of the operating microscope or not at 5 minutes after sub-Tenon's anesthesia, and at the end of phacoemulsification, core vitreous removal, peripheral vitreous removal and the whole surgery, with their contralateral eyes being covered tightly and no photobleaching...

PURPOSE: The aim of this study is to report surgical outcomes in patients undergoing phacoemulsification surgery (PE) with versus without ophthalmic viscosurgical devices (OVDs). METHODS: This is a comparative case series study. In total, 145 patients who performed PE with OVDs in 68 eyes (Group 1) and without OVD in 77 eyes (Group 2) were enrolled. A comprehensive ophthalmological examination was performed including slit-lamp, fundus examination. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) specular endothelial microscopy (SM), and ultrasound pachymetry (UP) were also measured before surgery and at four-time points postoperatively...

A patient with keratoconus underwent a penetrating keratoplasty (PK) in his right eye. This failed after 12 years following phacoemulsification surgery. A Descemet's stripping endothelial keratoplasty (DSEK) was carried out which failed and detached after 4 months. Subsequently, a second DSEK was performed which failed after 2 months but remained attached. This graft was retained in the cornea and a third DSEK button was placed without removing the failed DSEK graft. The cornea cleared well and patient's vision was 6/9 at 18 months postsurgery...

Purpose. We evaluated the efficacy and safety of a mechanical device, the P-chute, in corneal endothelium preservation during phacoemulsification in a rabbit model. Methods. Twenty-four rabbits were randomly assigned into 2 groups. One eye of each rabbit underwent phacoemulsification that simulated the removal of a dense nucleus, with or without the P-chute. Serial slit-lamp examinations, anterior segment optical coherence tomography (ASOCT) scans, and specular microscopy were performed. Three rabbits from each group were sacrificed on postoperative days (PODs) 1, 5, 7, and 14...
