Rationale: Here we report the case of a patient who required closure with an autologous scleral patch graft during reoperation after developing marked scleral thinning in the late stage after pars plana phacoemulsification and aspiration (PPPEA). To the best of our knowledge, this is the first reports of the procedure being used for the treatment of a thinned scleral section post PPPEA. Patient concerns: This study involved a 73-year-old woman who had undergone vitreous surgery combined with PPPEA for retinal detachment in her right eye 8 years earlier and subsequently underwent intraocular lens (IOL) ciliary sulcus suture fixation. Diagnoses: She became aware of visual disturbance in her right eye and slit-lamp examination revealed the dislocation of the IOL. Interventions: To remove the dislocated IOL and resuture the nasal loop back onto the ciliary sulcus of the patient's right eye, a 25-guage trocar was placed on the superior temporal side. Outcomes: Subsequent removal of the trocar from the patient's right eye left an approximately 3-mm-wide oval-shaped gap at the trocar insertion site due to extreme thinning of the sclera in that area; that is, the location where the PPPEA was performed. Since suture fixation failed to stop intraocular fluid leakage, an inferior free half-thickness scleral flap was created to patch the scleral wound. Postsurgery, the leakage in that eye stopped and the intraocular pressure was stable. No complications were observed during the 1-year-postoperative follow-up period. Lessons: Since thermal injuries during PPPEA may lead to postoperative scleral thinning, surgeons should avoid the site of a prior PPPEA when constructing a scleral wound during reoperation.
