Visual and refractive outcomes following implantation of a new trifocal intraocular lens.

Background: Independence from all optical aids, and freedom from unwanted symptoms, following cataract and lens surgery remains the ultimate goal of both patient and surgeon. The development of trifocal IOL technology provides an ever-increasing range of options. The purpose of our study is to understand the predictability, safety and efficacy of a new trifocal intraocular lens (IOL) following cataract or refractive lens exchange (RLE) surgery.

Oral antivirals for preventing recurrent herpes simplex keratitis in people with corneal grafts.

Background: Ocular herpes is a viral infection of the eye caused by the herpes simplex virus (HSV), a double-stranded DNA virus. Corneal scarring caused by herpes simplex keratitis (HSK) is the leading infectious cause of penetrating corneal graft in high-income countries. Acyclovir is an antiviral drug known to have a protective effect against recurrences in herpetic eye disease.

Design and validity of a miniaturized open-field aberrometer.

Purpose: To design and validate a new miniaturized open-field wavefront device that can be attached to an ophthalmic surgical microscope or slitlamp.

Setting: Solihull Hospital and Aston University, Birmingham, United Kingdom.

Design: Comparative noninterventional study.

A 43-year-old woman on triptorelin presenting with pseudotumor cerebri: a case report.

Introduction: To the best of our knowledge, this is the first time triptorelin has been reported to cause benign intracranial hypertension.

Case Presentation: A 43-year-old Caucasian woman who suffered from chronic menorrhagia was started on triptorelin, a gonadotrophin-releasing hormone analogue. Three days later, she developed gradually worsening headaches accompanied by bilateral visual disturbance.

Outcomes of deep anterior lamellar keratoplasty following successful and failed 'big bubble'.

Aim: The most popular technique for deep anterior lamellar keratoplasty (DALK) is the 'big bubble' (BB) technique wherein air is injected in the cornea to create a bubble that separates Descemet's membrane (DM) from the stroma. An attempt to create a BB often results in the cornea being filled with numerous small bubbles without the formation of a BB. Manual dissection is then required to complete the procedure.

Sequential leukemic infiltration and human herpesvirus optic neuropathy in acute lymphoblastic leukemia.

Leukemic infiltration is a common cause of optic disk swelling in a patient with acute lymphoblastic leukemia (ALL). Recurrence of optic disk swelling in a patient with previous leukemic infiltration carries a grave prognosis when it is associated with recurrent central nervous system disease. We report a case of recurrent swelling of an optic disk in a patient with T-cell ALL who had previously been treated for CNS relapse with optic nerve involvement.

Removal of lens epithelial cells and the effect on capsulorhexis size.

Purpose: To assess the long-term effects of lens epithelial cell (LEC) removal on capsulorhexis opening size.

Setting: Dorset County Hospital, Dorchester, United Kingdom.

Methods: This prospective randomized control study included 39 eyes of 38 patients.
