A group of 23 children with traumatic pseudophakia was evaluated. Intraocular lens (IOL) implantation was performed as a primary procedure, immediately after aspiration of the traumatic lens, in 7 cases and as a secondary procedure in 16 cases. The mean followup was 6.5 years, varying from 1.5 to 11 years. A visual acuity of 0.7 or more was achieved in 3 of the 8 patients under 7 years of age and in 13 of the 15 cases from 7 to 14 years of age. Awaiting longer follow-up results of epikeratophakia in children we advise to perform early IOL implantation in children under 7 years of age, combined with a rigid amblyopia treatment scheme. In children older than 7 years of age we prefer to try the use of contact lenses first and preserve IOL implantation for selected cases.
Two juvenile, male, captive-born lowland gorillas (Gorilla gorilla gorilla) with the same father but different mothers developed bilateral cataracts. The cataracts were surgically removed within 6 yr and 3 mo, respectively, of diagnosis, and foldable intraocular lenses were implanted. Although vision was not restored in one eye with a mature, 6-yr-old cataract in gorilla A, surgical intervention on the other eye was performed before a complete cataract developed, and vision was fully restored. Gorilla B was treated at the age of 17 mo, and normal visual development proceeded in both eyes. This animal developed bilateral after-cataract and therefore needed a second intervention in both eyes using Nd:YAG laser treatment. The genetic component of juvenile cataracts should be considered in breeding management programs.
Trypan blue staining of the anterior lens capsule may therefore be a safe technique to facilitate the performance of a capsulorhexis in the absence of a red fundus reflex.
We compared the surgically induced astigmatism after standard extracapsular cataract extraction (ECCE) with the astigmatism following cataract extraction by phacoemulsification. The surgically induced corneal astigmatism was assessed on several occasions, ranging from one day to one year postoperatively. After phacoemulsification, this astigmatism was considerably slighter than after ECCE on day 1 postoperatively and after two and six weeks. However, one year postoperatively, this difference was less clear. We then measured slight against-the-rule astigmatism for both surgical techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
