All subjects underwent a standard three -port 20G pars plana vitrectomy (PPV) with lensectomy and silicone oil tamponade. Mean follow -up time was 8 months (rang from 4 to 19 months). The primary and final anatomic success rate, visual acuity and final intraocular pressure (IOP) were recorded and analyzed. ·RESULTS: Of 21 subjects, 8 were women and 13 were men. Age at presentation ranged from 22 to 75 years (mean 57.4 years). The presenting vision ranged from light perception to 0.15. The initial IOP ranged from 3mmHg to 12mmHg (mean 6.2mmHg). All eyes were phakic except one pseudophakic. No intraocular lens was implanted during the primary surgical intervention. Fifteen of 21 (71.4%) eyes had retina reattached after one operation. Six eyes had recurrent inferior retinal detachment due to proliferation. Five of them were successfully reattached after one or more additional operations. Mean IOP at final follow -up was 15.2mmHg (range from 8mmHg to 20mmHg). One case declined for further operation. The final reattachment rate was 95.2%. Visual acuity improved in 19 (90.5%) eyes, was unchanged in 1 (4.8%) eye and decreased in 1 (4.8%) eye.·CONCLUSION: Combination of vitrectomy, lensectomy and silicone tamponade is an effective method in treating RRD associated with CD, reducing the incidence of postoperative hypotony.展开更多

Posterior PHPV was treated with lensectomy,posterior vitrectomy,retinal photocoagulation,and IOL implantation or silicone oil tamponade. Visual acuity（VA）,pattern visual evoked potential（P-VEP）,anatomic recovery,postoperative complications,and amblyopia outcome were examined.Subjects were followed-up for 3-48 mo after surgery.RESULTS：Of the 30 patients（33 eyes）with congenital cataract and PHPV included（average age,39.30±35.47mo）,9 eyes had anterior PHPV and 24 had posterior PHPV. Thirty-two eyes were surgically treated. Eyes with anterior PHPV received an IOL during one-stage（6 eyes）and twostage（3 eyes）implantation. Postoperative complications included retinal detachment（1 eye）and recurrent anterior chamber hemorrhage（1 eye）. In eyes with posterior PHPV,6 and 11 eyes received IOLs in one-and two-stage procedures,respectively. Silicone oil was retained in 2 eyes,and IOLs were not implanted in 4 eyes. VA significantly improved in 25 eyes following operations and 3-48 mo of amblyopia treatment. P-VEP P_（100） was improved following surgery in both PHPV types.CONCLUSION：Our surgical strategies are appropriate and effective for anterior and posterior PHPV. Early surgical intervention and amblyopia therapy result in positive treatment outcomes.展开更多

Refraction of all selected eyes should be-8.00 D sphere or more with less than-6.00 D cylinder and could be corrected two lines or more with spectacles or contact lenses. All studied eyes underwent a two-stage approach treatment： first refractive lens exchange and aspherical IOL implantation followed, after at least 3 mo, by WFGPRK. Pre and postoperative complete ophthalmological examination were performed. Topographical, visual and aberrometric results were recorded and evaluated during 6 mo follow up period. Moreover, patient satisfaction and other subjective outcomes were also analyzed.RESULTS： The 13 eyes of 11 patients diagnosed with stable keratoconus and aged from 39 to 49 y（42.4±6.2 y） were enrolled in the study. At baseline, 8 eyes had grade I and 5 eyes had grade II keratoconus. The manifest sphere was-10.3±4.2 D（ranged from-8.0 to-14.0 D） and the manifest cylinder was-4.2±1.2 D（ranged from-1.75 to-5.50 D）. After the two-stage procedure, sphere and cylinder reduced significantly to-0.43±0.22 D and-1.3±0.72 D respectively（P〈0.001）. There was also a highly significant improvement in the mean uncorrected distance visual acuity（UDVA） from logMAR 1.41±0.49 preoperatively to 0.51±0.16 postoperatively（P〈0.001） and the mean corrected distance visual acuity（CDVA） from 0.76±0.24 preoperatively to 0.49±0.13 after the operation（P〈0.001）. All aberrometric and mesopic vision parameters and most of the topographical indices demonstrate展开更多
