Aim: To describe a new method of removing dislocated nuclear fragments smaller than one-fourth the size of the lens nucleus through the sclerocorneal incision made for cataract surgery.
Methods: Dislocated lens nuclear fragments on the surface of the retina were removed from six eyes of six consecutive patients. An anterior vitreous cutter with a 27-gauge chandelier endoilluminator (Twinlight illumination) tied to its sleeve was inserted into the eye through the incision made for cataract surgery and used for core vitrectomy. A fragmatome with another 27-gauge chandelier endoilluminator (Twinlight illumination) fibre was used to grasp and move the larger dislocated nuclear fragments into the anterior chamber where they were divided and removed.
Results: All dislocated nuclear fragments were removed through the incision for cataract surgery, and a posterior chamber lens was implanted in each patient without major complications.
Conclusions: The procedure can be used to remove dislocated lens nuclear fragments from the surface of the retina through the incision for cataract surgery. Neither a second surgery, which would require three ports, nor the body of instruments for vitreal surgery are needed with this procedure.

Aim: To measure the optimal anterior chamber pressure (ACP) for safe phacoemulsification using a new tube chamber system with internal pressure measurement function in the porcine eye.
Methods: The 20-gauge and 21-gauge straight tips with yellow and orange sleeves, respectively, were covered by a test chamber combined with a pressure sensor for measuring ACP. This was measured for 20s from 10s after starting aspiration in the linear mode using vacuum levels of 200 and 150 mm Hg with a 20-gauge tip, and 300 and 250 mm Hg with a 21-gauge tip.

Objectives: The aim of the study was to evaluate anatomical and functional outcomes of the Smaller-Incision New Generation Implantable Miniature Telescope (SING IMT™) in patients with bilateral advanced age-related macular degeneration (AMD).
Methods: This non-comparative retrospective single-surgeon interventional case series included patients with bilateral late-stage AMD who underwent cataract surgery and SING IMT™ implantation at the Sant'Anna University Hospital, University of Ferrara, Italy. The main outcome measures included corrected distance (CDVA) and near visual acuity (CNVA), endothelial cell loss (ECL), and incidence of complications.

Purpose: To quantify the effect of cataract surgery on cornea shape.
Methods: Patients undergoing cataract surgery with standardised 2.75 mm surgical incisions at 110 degrees with a side port at 50 degrees were included.

Purpose: Current treatments for retinoblastoma facilitate globe salvage but can result in vitreoretinal disorders that may require surgery. There is controversy on surgical approaches in eyes with retinoblastoma. Here we describe a transcorneal vitrectomy approach that avoids the use of chemotherapy or cryotherapy.
View Article and Find Full Text PDFPurpose: To evaluate residual refractive errors after intraocular lens (IOL) extraction and the safety and effectiveness of refractive correction procedures.
Methods: The eligibility criteria for this systematic review were patients who had undergone cataract or clear lens extraction and had experienced residual refractive error. All study designs were considered for inclusion and non-English publications, non-peer reviewed articles, books, and systematic reviews were excluded.
