Microspherophakia constitutes a rare, mostly bilateral anomaly of the crystalline lens, which is characterized by the presence of an increased lens thickness and reduced equatorial diameter. It is frequently associated with lens subluxation, translating into a high degree of variable lenticular myopia and defective accommodation. The purpose of this report is to describe the treatment of a three-year-old female patient with microspherophakia, with the scleral fixation of an intraocular lens using the z-suture technique. A three-year-old female patient with Marfan Syndrome presented with high bilateral myopia and esotropia. Lens subluxation was perceived, and she was proposed for bilateral surgery. Scleral fixation of the intraocular lens was performed using the z-suture technique. During the five-year follow-up period, she maintained a best-corrected visual acuity of 20/20 in both eyes wearing bifocal glasses. Microspherophakia is a rare but impactful condition, frequently related to severe and variable refractive error due to the lens shape and zonule instability. Intraocular lens implantation in the capsular bag is usually impossible, and scleral fixation is a valid alternative. The z-suture technique avoids suture knots and the need for intrascleral flaps, reducing the risk of suture-related complications.
