537 Implications of Covid-19 on Vitreoretinal and Cataract Surgery

Vitreoretinal influences on lens function and cataract.

The lens is composed of a thin metabolically active outer layer, consisting of epithelial and superficial fibre cells. Lying within this outer shell are terminally differentiated, metabolically inactive fibre cells, which are divided into an outer cortex and central nucleus. Mature fibre cells contain a very high protein concentration, which is important for the transparency and refractive powe...

Cataract surgery and quality of life implications

Cataract surgery in the developed world has undergone a revolution over the last 20 years. An operation which used to require a stay in hospital and long visual rehabilitation is now a quick day-case procedure with immediate benefits. As with any surgery there is an associated morbidity, but there is now the potential to provide cataract surgery at an earlier stage of cataract maturation and sa...

Cataract formation following vitreoretinal procedures

PURPOSE To evaluate the incidence and prevalence of cataract formation, progression, and extraction in patients that underwent vitreoretinal procedures and to evaluate factors that can potentially predispose patients to postoperative cataracts. MATERIALS AND METHODS The medical records of consecutive patients who underwent vitreoretinal surgery at the Yale Eye Center with at least 6 months of...

Minimally Invasive Vitreoretinal Surgery

Pars plana vitrectomy (PPV) was introduced almost 40 years ago. 1 In the 1980s and 1990s, three-port PPV with 20-gauge (G) instruments was the norm. In 2002, 25-gauge transconjunctival sutureless vitrectomy (TSV) was introduced.2,3 This system permits threeport PPV using microcannulas, trocars, and 25-G instrumentation without requiring sutures to close the sclerotomies. Subsequently, a similar...
