Corneal characteristics in children with Marfan syndrome with or without ectopia lentis

open access: yesPediatric Investigation, Volume 9, Issue 2, Page 160-166, June 2025.
Children with Marfan Syndrome who have dislocation of the natural lens of the eye also have abnormalities of eye shape and size. These abnormalities are not apparent in Marfan's children who do not have lens dislocation, implying that the children with lens dislocation have a more severe genetic defect of fibrillin proteins.

Technological characteristics of cataract surgery in eyes with posterior chamber phakic intraocular lens implanted previously

open access: yesJournal of Ophthalmology, 2016
Introduction. Implantation of phakic intraocular lenses (PIOL) is used for the correction of high myopia. The problem of PIOL implantation is that cataract may develop in a long-term period after surgery due to the contact of constructive PIOL elements ...

The effectiveness of early lens extraction with intraocular lens implantation for the treatment of primary angle-closure glaucoma (EAGLE): Study protocol for a randomized controlled trial [PDF]

open access: yes, 2011
BACKGROUND: Glaucoma is the leading cause of irreversible blindness. Although primary open-angle glaucoma is more common, primary angle-closure glaucoma (PACG) is more likely to result in irreversible blindness. By 2020, 5·3 million people worldwide will
