Lensectomía refractiva en coloboma de iris / Refractive lensectomy for iris coloboma

RESUMEN El coloboma de iris es un defecto congénito, que se describe como un orificio, fisura o hendidura en dicha estructura.​ Esta condición tiene la posibilidad de ser hereditaria o aparecer sin historia familiar previa. Se presenta un caso de un paciente de 51 años de edad con coloboma bilateral de iris asimétrico e hipermetropía, quien acudió a la consulta médica con el deseo de independizarse de su corrección óptica habitual. Se propuso cirugía facorrefractiva de ambos ojos con pupiloplastia del ojo derecho, en el que se obtuvieron resultados visuales satisfactorios después de la intervención quirúrgica(AU)

ABSTRACT The iris coloboma is a congenital defect, present since birth, which is described as a hole, fissure or cleft in the mentioned structure. This condition has the possibility of being inherited or can appear without previous family history. The case is presented of a 51-year-old patient with bilateral asymmetric iris coloboma and farsightedness. The patient went to the doctor's office with the desire to become independent of his usual optical correction. Facorrefractive surgery of both eyes with pupilloplasty of the right eye was proposed, in which satisfactory visual results were obtained after the intervention(AU)

Modified sewing machine technique for iridodialysis repair, intraocular lens relocation, iris coloboma repair, Cionni ring fixation, and scleral-fixated intraocular lens

The purpose of this study is to report the modification of sewing machine technique for iris dialysis repair (MSMT) and its usefulness in managing other conditions such as intraocular lens (IOL) subluxation, iris coloboma, Cionni ring for zonular dialysis, and for scleral-fixated IOL. MSMT was based on sewing machine principle using a prethreaded 26G/30G needle with prolene suture for minimally invasive iris dialysis repair in a closed chamber manner. So far, eight patients (trauma � 3, surgical complication � 5) underwent this procedure. This technique is further modified to extend its use for IOL relocation � 2, iris coloboma repair � 3, and Cionni ring fixation for zonular dialysis � 2, SFIOL � 5 patients. All 20 patients had good visual recovery and cosmetic outcome with minimal morbidity. To conclude, MSMT offers cost -effective, minimally invasive, easy to learn procedure with a potential to tackle several problems related with cataract surgery and iris defects, which even an average cataract surgeon can learn to perform when required. Further comparative studies with conventional techniques with large sample size are required to standardize this procedure.
