Purpose: To evaluate the effect of one-site combined phacoemulsification and trabeculectomy in the management of cataract patients with drug-controllable glaucoma. Methods : Twenty-four cases (25 eyes) of cataract patients with glaucoma whose intraocular pressure could be controlled by drugs were observed. All had undergone one-site combined phacoemulsification and trabeculectomy. Intraocular pressure and visual acuity were ***: The follow-up was 1-21 months. Postoperative visual acuity was 0.4-0.6 in 9 eyes, 0.7-0.9 in 7 eyes and 1.0 or better in 9 eyes. Postoperative intraocular pressure was 2.17±0.764kPa (16.28±5.73mmHg), 1.83±0.90kPa (13.74 ± 6. 77mmHg) lower than that before surgery (t= 11.89, P<0.01). Only one eye needed one drug to control intraocular pressure after ***:One-site combined phacoemulsification and trabeculectomy is a safe, effective and convenient technique for the management of cataract patients with drug-controllable glaucoma. .

Purpose: To observe the difference of the effects of PMMA and foldable intraocular lenses (IOLs) trans-sclerally fixed in pediatric eyes.Methods: Thirty-two children (43 eyes) who had undergone trans-scleral fixation of IOL were retrospected, of whom 5 children were implanted PMMA IOL in both eyes, 6children were implanted PMMA IOL in one eye and foldable IOL in the other eye, 12children were implanted foldable IOL in one eye and 9 chilrden were implanted PMMA IOL in one eye. Mean age was 5.3 years ( range 2.5 ～ 12 years ). Twelve children had traumatic cataract and the others congenital cataract before lens extraction.Results: Foldable group (18 eyes ): Mean follow-up was 12.1 months. Visual acuity (VA): compared with the best corrected VA before IOL fixation, postoperative best corrected VA improved in 16 eyes, remained unchanged in 2 eyes. In 14 eyes, one or two stitches were needed to seal the incision. Complications: Severe anterior chamber reaction was seen in 3 eyes. Intraocular bleeding was found in 3 eyes. IOL decentration was detected in 1 eye. Iris capture of IOL was seen in one eye. PMMA group (25 eyes ):Mean follow-up was 20.3 months. Visual acuity (VA): compared with the best corrected VA before IOL fixation, postoperative best corrected VA improved in 19 eyes,remained unchanged in 5 eyes and got worse in one eye. In 24 eyes, one to three stitches were needed to seal the incision. Complications: Severe anterior chamber reaction was seen in 5 eyes. Intraocular bleeding was found in 4 eyes. IOL decentration was seen in one eye. Iris capture of IOL was seen in 3 eyes. Intraocular pressure elevated in one eye.Conclusion: Our study shows that trans-scleral fixation of IOL is a safe procedure in pediatric eyes. Foldable IOL showed similar effect compared with PMMA IOL in pediatric trans-scleral fixation. Eye Science 2001; 17:61 ～ 64.

Purpose: To evaluate the influence of cataract surgery on eyes of children between 1-5 years *** and Methods : Forty- seven cases of pediatric cataract, including 31 cases of bilateral congenital cataract and 16 cases of unilateral posttraumatic cataract, were retrospected. Of the 31 cases of congenital cataract, 19 cases (group l) had undergone cataract extraction with intraocular lens(IOL) implantation, 12 (group 2) had undergone cataract extraction without IOL implantation. Each of them had their two eyes operated seperately at an interval of 1 year or longer. Of the 16 cases of posttraumatic catatract,6 (group 3) had undergone cataract extraction with IOL implantation and 10 (group 4) had undergone cataract extraction without IOL implantation. Mean age at the time of interested surgery was 2.9 years ( range from 1.1 to 5.1 years) . Ocular axial length of both eyes measured by A-scan ultrasonography before and after the surgery of the earlier operated eye in the congenital groups and the

Purpose: To develop a new technique for fixation of posterior chamber intraocular lens (IOL) in the absence of posterior capsule *** and Methods: We performed non-trans-scleral fixation of intraocular lenses on 24 cases (24 eyes) without posterior capsule support. Two scleral flaps with limbal incisions and two peripheral iridectomies were made at 1 o' clock and 7 o' clock positions respectively. A suture-leading needle was used to lead the prolene suture from the limbal incision and iridectomy on one side through the iridectomy and limbal incision on the other side. Intraocular lens (IOL) was then fixed in the ciliary sulcus. Results: After a mean follow-up of 6. 6 months (range from 3 to 14 months), corrected visual acuity of 16 cases (16 eyes,66. 7% ) got 0.5 or better. Postoperative complications included discoria (4 eyes) , surface membrane formation ( 1 eye ), choroidal detachment (1 eye) and tilt of IOL (1 eyes),but all were not severe. Conclusion: In some situations such as low

We studied the corneal curvature of 161 eyes in 101 patients, aged from 50 to 80 years (mean: 63 years), with senile cataract using the Topographic Modeling System (IMS) preoperatively. The results revealed that mean surface asymmetry index (SAD was 0. 36 and mean surface regularity index (SRI) 0. 79. Simulated keratometry reading (Sim K) was 44. 46 D, and 43. 56 D. Minimun K reading was 42. 60 D. The same patterns of corneal topography in both eyes were 50% in 60 patients who had binocular examination....
