En el pasado surgieron serias complicaciones asociadas a esta intervención quirúrgica, como desprendimiento de retina y glaucoma. El avance de las técnicas quirúrgicas en las últimas décadas ha brindado mayor seguridad para la cirugía de esta afección del cristalino. Se presenta una paciente femenina de 47 años aquejada de disminución de la visión. Al examen oftalmológico se encuentra subluxación superior del cristalino bilateral. Previa discusión con la paciente de los posibles escenarios a presentarse durante la cirugía, se le sugiere una facoemulsificación bilateral secuencial del cristalino conservando el saco capsular mediante la colocación de un anillo de tensión capsular fijado a la esclera más implante de lente intraocular plegable en el saco capsular. Se realiza primeramente cirugía del ojo izquierdo y se presenta un desgarro radial de la rexis con extensión posterior, por lo que se varía el abordaje quirúrgico y se fija el implante al iris. Un mes después se realiza cirugía del ojo derecho siguiendo el plan quirúrgico inicial sin complicaciones. La recuperación visual fue satisfactoria (0,7 en cartilla de Snellen) en ambos ojos y se demostró la efectividad de ambas alternativas quirúrgicas. La planificación correcta de la técnica quirúrgica y de las posibles modificaciones ante circunstancias sobrevenidas, así como la oportuna información preoperatoria y la experiencia del cirujano resultan fundamentales para alcanzar el éxito quirúrgico, la recuperación funcional y la satisfacción del paciente.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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.]]></p></abstract>
