Purpose: To report a novel technique for refixation of the dislocated CZ70BD intraocular lens. Methods: Posterior vitrectomy is performed with a 23-gauge or 25-gauge pars plana vitrectomy system with chandelier illumination. One needle of a double-arm 9-0 prolene needle is passed through the sclera 1.5 mm postlimbus. The needle is retrieved through the corneal paracentesis using a 27-G needle, and the suture is then cut. The suture end is passed through the eyelet of the dislocated CZ70BD intraocular lens inside the vitreous cavity. This is aided with a pair of 27-G MaxGrip forceps, which is inserted through a 27-G sclerostomy site at the intended scleral outlet. After passing the suture through the eyelet, the suture is pulled out at the 27-G sclerostomy site and a knot is tied and rotated. Similar procedure is performed for the second haptic if necessary. Results: Seven eyes were successfully operated on using this technique with a mean follow-up of 12.4 months. There was significant improvement in the best-corrected visual acuity after the operation (P = 0.016). Postoperative intraocular lens centration and alignment were satisfactory. One patient developed macula-on retinal detachment 1 month after the operation, which was successfully repaired without loss in the best-corrected visual acuity. Conclusion: The described novel technique is effective for refixation of dislocated CZ70BD intraocular lens.
Conventional management modalities of CRAO include ocular massage, intraocular pressure-lowering drugs or techniques (such as glaucoma eyedrops, intravenous or oral Diamox, intravenous mannitol, and anterior chamber paracentesis, and rebreathing into a bag to increase carbon dioxide concentration that causes vasodilatation). Newer treatment modalities include intravenous thrombolysis with tissue plasminogen activator 5-7 and intra-retinal arterial
We report two rare cases of macular fold development after membrane peeling operation for epiretinal membrane. Patient 1 developed both inner and outer retinal folds, and patient 2 developed inner retinal fold; both were partial thickness macular folds. There was no evidence of retinal detachment or any preoperative macular fold. These configurations of retinal folds after macular epiretinal membrane surgery have not been reported before. In patient 1, four retinotomy sites were required to induce a complete macula detachment, as the retina was abnormally adherent than usual. In patient 2, no macular detachment was induced, and no intravitreal tamponade was used. Soft-tip cannula was used to relieve the inner retinal attachments. To the best of our knowledge, this is the first reported case using this method to successfully manage a retinal fold. This technique avoids the potential risks associated with retinotomies, macular re-detachment, and intravitreal tamponade. Both patients achieved resolution of macular folds and improvement in visual acuity.
