HERNANDEZ LOPEZ, Iván et al. Ectopia lentis and surgical solutions in cataract surgery. Rev Cubana Oftalmol [online]. 2019, vol.32, n.1  Epub June 06, 2019. ISSN 1561-3070.

Crystalline lens removal in patients with ectopia lentis is a challenge for eye surgeons. Serious complications, such as retinal detachment and glaucoma, were associated in the past to this surgical procedure. However, the progress in surgical techniques achieved in recent decades provides greater safety in the surgical treatment of this lens disorder. A female 47-year-old patient attends consultation complaining of vision reduction. Ophthalmological examination reveals bilateral crystalline lens upper subluxation. The possible scenarios to occur during surgery are discussed with the patient, and it is suggested that she undergoes sequential bilateral lens phacoemulsification preserving the capsular bag with the placement of a capsular tension ring fixed to the sclera plus implantation of a foldable intraocular lens in the capsular bag. The first eye to be operated on is the left eye, and radial tear of the rhexis with posterior extension occurs. Therefore, the surgical approach is changed and the implant is fixed to the iris. Surgery of the right eye is performed one month later, following the initial surgical plan without any complications. Visual recovery was satisfactory (0.7 by the Snellen chart) in both eyes, proving the effectiveness of both surgical alternatives. Correct planning of the surgical technique and its possible modifications in response to unexpected circumstances, alongside timely preoperative information and the surgeon's experience, are all crucial to achieve surgical success, functional recovery and patient satisfaction.
