1/3. Choroidal effusions and hypotony caused by severe anterior lens capsule contraction after cataract surgery.PURPOSE: To report the clinical features and management of two patients with pseudophakic anterior capsule contraction with secondary tractional ciliary body detachments and hypotonous choroidal effusions. methods: case reports. RESULTS: In two eyes of two patients with pseudophakia, severe anterior lens capsule contraction and tractional ciliary body detachments, anterior capsulotomy (one Nd:YAG laser, one surgical), was followed by resolution of the ocular hypotony and resolution/nonrecurrence of the choroidal effusions. In both cases, continuous curvilinear capsulorhexis was used during cataract surgery. CONCLUSION: Anterior capsule contraction following pseudophakia may result in tractional ciliary detachment and secondary ocular hypotony. Radial anterior capsulotomy appeared to be effective in both cases.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
2/3. Pars plana vitrectomy for persistent, visually significant vitreous opacities.PURPOSE: To evaluate the role of vitrectomy in patients with persistent, visually disabling vitreous opacities. methods: Six consecutive eyes of five men (age 58-66 years) with pseudophakia or aphakia and vitreous opacities resulting in visual symptoms for more than 1 year that underwent vitrectomy were retrospectively reviewed. Postoperative questionnaires regarding functional performance and quality-of-life issues were completed by the participants to assess subjective patient satisfaction. RESULTS: Postoperative Snellen visual acuity was improved or equal to preoperative acuity in all cases (8-44 month follow-up) and there were no surgical complications. All patients expressed high satisfaction with overall visual function. Analysis of the National eye Institute Visual Function Questionnaire-39 indicated that general vision, near activities, distance activities, mental health, role difficulties, and peripheral vision were significantly improved (P < 0.05) following surgical intervention. CONCLUSIONS: vitrectomy may be indicated in a select group of patients with visually disabling vitreous floaters, although objective assessment of visual dysfunction from vitreous floaters requires further evaluation.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
3/3. visual acuity, contrast sensitivity, reading speed, and wavefront analysis: pseudophakic eye with multifocal IOL (ReSTOR) versus fellow phakic eye in non-presbyopic patients.PURPOSE: To compare the visual performance in the pseudophakic eye and the phakic eye in four patients who underwent unilateral intraocular lens (IOL) implantation. methods: Four patients presenting with unilateral cataract underwent ReSTOR (Alcon laboratories, Ft Worth, Tex) IOL implantation in their nondominant eye, targeting emmetropia. RESULTS: Uncorrected near visual acuity was >20/32 in all operated eyes and best spectacle-corrected distance visual acuity was 20/16 for two eyes, 20/25 for one eye, and 20/32 for one eye. reading speed was similar between the eyes, but not for critical print size. contrast sensitivity was lower in the pseudophakic eyes. Wavefront analysis showed no considerable difference in total high order aberrations, coma, and spherical aberration between eyes for all patients. CONCLUSIONS: In young patients with unilateral cataract surgery, unilateral multifocal IOL implantation provides satisfactory visual acuity and may be considered an alternative treatment option in this patient population.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
