RESUMO
The aim of this study is to describe a modified technique for internal refixation of dislocated scleral-sutured polymethylmethacrylate (PMMA) intraocular lenses (IOLs) with eyelets. Three-port pars plana vitrectomy was performed. Through the scleral fixation site, a 30-gauge needle loaded with an 8-0 polypropylene suture was inserted into the vitreous cavity. The suture end was passed through the eyelet of IOL with 25-gauge forceps. Next, it was guided out of the eye through the original scleral fixation point. The end of the exterior suture was buried with a flapless intrascleral knotting technique. Six eyes of six patients were successfully treated with this technique and followed up for 6-12 months postsurgery. In all cases, there was significant improvement in uncorrected visual acuity. IOLs were stable with proper centration and no major complications. This modified technique offers an effective and minimally invasive surgical alternative for refixation of dislocated scleral-sutured PMMA IOLs with eyelets.

PURPOSE: To describe a technique of internal limiting membrane (ILM) peeling without vitrectomy for the treatment of laser-induced macular holes in two children. METHODS: ILM peeling was performed under the vitreous hyaloid, and the vitreous was retained. Slit lamp and optical coherence tomographic examinations were performed before and after surgery. RESULTS: Macular holes were closed with different patterns at different time in the two patients, while visual acuity improved significantly in both of them eventually. CONCLUSION: The technique of ILM peeling in the absence of vitrectomy can promote the closure of laser-induced macular holes and minimize the surgical procedure, with few vitrectomy complications in pediatric patients. The closure pattern may vary on account of different injury sources and extents.
