Cataract surgery in a patient with anterior megalophthalmos:a case report and literature review
Anterior megalophthalmos is a rare congenital enlargement of the anterior segment,characterized by bilateral nonprogressive megalocornea(diameter≥12.5 mm),extremely deep anterior chamber,normal or moderate thinning of the cornea,and elongation of the ciliary ring.Cataract and lens dislocation are the main causes of decreased vision in patients with AM.However,cataract surgery on patients with AM are challenging due to the anatomical abnormalities.This case reports a 48-year-old male patient diagnosed with AM and cataract,who successfully underwent a manual small incision cataract extraction combined with intraocular lens implantation.Finally,our patient showed a good visual outcome with a well centered IOL and without obvious refractive error.In this typical AM case,we reviewed and summarized the clinical characteristics and the challenges of surgical treatment so that other ophthalmologists can learn about this disease.
