A multi-centre interventional case series of 259 ab-interno Xen gel implants for glaucoma, with and without combined cataract surgery.

Aims: To assess the efficacy of Xen in reducing intraocular pressure (IOP) in varying glaucoma subtypes. To assess the effect of combined phacoemulsification. To determine the frequency of complications and explore further bleb management needed.

Ratios for double silicone oil Endotamponade - in vitro observations may assist with ratio selection.

Background: Silicone oil tamponade is more frequently reserved for cases of complex retinal detachment. We describe the effects of different variations in oil ratios with the relatively unknown technique of double oil tamponade.

Methods: Retrospective case note review of nine patients with complex rhegmatogenous retinal detachment (RD).

High altitude subhyaloid hemorrhage.

Subhyaloid hemorrhages can occur as a result of exposure to high altitude. We hereby report a clinical picture of subhyaloid hemorrhage associated with high altitude. The case demonstrates optical coherence tomography findings that aid diagnosis of subhyaloid hemorrhage.

A novel technique of rescuing capsulorhexis radial tear-out using a cystotome.

Unlabelled: PART 1:

Purpose: To demonstrate a capsulorhexis radial tear out rescue technique using a cystotome on a virtual reality cataract surgery simulator and in a human eye. PART 2:

Method: Steps: When a capsulorhexis begins to veer radially towards the periphery beyond the pupillary margin the following steps should be applied without delay. 2.
