ABSTRACT
PURPOSE: To introduce a more efficient and time-saving scleral fixation technique for a posterior chamber foldable intraocular lens and to report the clinical results. METHODS: A foldable acrylic 3-Piece IOL was sutured to the sclera via a small corneal incision. The guiding hollow needle was not used, which differs from other ab externo techniques. Instead, the curved long needle was directly pulled out through the cornea. The scleral flap was not used to bury the scleral suture knot; Instead, the scleral suture knot was translocated at the temporal area. RESULTS: A total of 30 cases were studied retrospectively. The mean follow-up period was 2 years. The IOL was correctly positioned in all cases. There were no major complications, such as endophthalmitis or suture erosion through the conjunctiva. CONCLUSIONS: Based on the authors' experience, the modified ab externo and one-knot technique is a faster and easier technique than the conventional ab externo technique.

PURPOSE: To report the first domestic case of choroidal neovascularization in a choroideremia patient treated with intravitreal bevacizumab injection. CASE SUMMARY: A 29-year-old male presented with a sudden decline in vision in the left eye. Fundus examination revealed areas of choriocapillaries and retinal pigment epithelium atrophy with macular hemorrhage. Fluorescein angiogram revealed vascular hyperfluorescence in the juxtafoveal area. Neurosensory detachment around the macula and increased central macular thickness was also observed using optical coherence tomography. Upon the diagnosis of choroideremia with choroidal neovascularization, the patient was treated with 1.25 mg intravitreal bevacizumab. Visual acuity improved after four injections of intravitreal Bevacizumab with improvement in both detachment and fluorescein leakage. CONCLUSIONS: In patients with choroideremia presenting sudden decline in vision, ophthalmologists should detect for possible choroidal neovascularization. The results from the present study show that judicious use of intravitreal Bevacizumab may be effective in such cases. Further studies with a large sample size and sufficiently long follow-up periods are required.

PURPOSE: To report a case of a macular hole resulting from accidental exposure to tattoo removal by the Q-Switched Nd:YAG laser, which was treated successfully by vitrectomy and silicone oil infusion. CASE SUMMARY: A 33-year-old man presented with decreased visual acuity after accidental exposure to a Q-Switched Nd:YAG laser. According to fundus examination, vitreous hemorrhage and macular edema were observed. After 21 days, a macular hole had developed which was treated by standard pars plana vitrectomy and gas tamponade. Unfortunately, closure was not obtained on the first attempt. Therefore, a second attempt using silicone oil infusion was performed. Four months after the initial visit, BCVA had increased to 20/50, and anatomical occlusion was achieved. CONCLUSIONS: The authors of the present study experienced an unusual case of macular hole developed from the Q-Switched Nd:YAG laser used to remove a tattoo. A satisfactory visual acuity was achieved after silicone oil infusion despite failure in the first surgery.
