Morgagnian cataract

Morgagnian cataract, a special form of corticonuclear cataract(11 Bardoloi N, Sarkar S, Burgute PS, Ghosh D, Deb AK. Capsular tension ring assisted phacoemulsification of Morgagnian cataract. Indian J Ophthalmol [Internet]. 2021;69(7):1781-5.), is a hypermature lens in which the cortex liquifies and the dense nucleus sinks inferiorly due to gravity(22 Terry JE, Miller M. Unilateral Morgagnian cataract. J Am Optom Assoc. 1977;48(8):1015-8.). In this type of cataract, the process of fiber dissolution accelerates and occurs en masse(11 Bardoloi N, Sarkar S, Burgute PS, Ghosh D, Deb AK. Capsular tension ring assisted phacoemulsification of Morgagnian cataract. Indian J Ophthalmol [Internet]. 2021;69(7):1781-5.). A spontaneous rupture can occur, causing severe intraocular inflammation(33 Ono T, Miyata K. Morgagnian cataract. JMA J [Internet]. 2022;5(3):379-80.); therefore, early treatment is required(33 Ono T, Miyata K. Morgagnian cataract. JMA J [Internet]. 2022;5(3):379-80.). However, surgery for this type of cataract has a high incidence of complications(44 Hua X, Dong Y, Wang L, Li Z, Du J, Chi W, et al. Intraocular lens implantation performed first to protect the posterior capsule in Morgagnian cataracts during phacoemulsification. Int J Ophthalmol. 2019;12(7):1215-8.) that include rigid anterior lens capsule, weak zonules, milky cortex with inadequate support for rhexis, and hard nucleus, leading to the risk of posterior capsular rupture, zonulodialysis, vitreous loss, nucleus drop, or inadvertent removal of the entire capsular bag(11 Bardoloi N, Sarkar S, Burgute PS, Ghosh D, Deb AK. Capsular tension ring assisted phacoemulsification of Morgagnian cataract. Indian J Ophthalmol [Internet]. 2021;69(7):1781-5.).
