Main outcome measures were preoperative and postoperative visual acuity, and complications both intraoperatively and postoperatively. RESULTS: Review of 22 consecutive patients identified best-corrected visual acuity(BCVA) improvement from 1.37±0.84 to 0.73±0.57 logarithm of the minimal angle of resolution(logMAR) after IOL implantation(P<0.001) with a mean follow-up was 16.55±5.86 mo. Average age at secondary IOL implantation was 41.05±15.41 mo. Three eyes(13.64%) achieved BCVA of 0.3 logMAR at the final visit. Transient intraocular pressure rise(4 eyes; 18.18%), postoperative increased inflammation(3 eyes; 13.64%) and postoperative hypotony(2 eyes; 9.09%) were common complications.CONCLUSION: Properly preservation of the anterior lens capsule during the primary surgery facilitated secondary sulcus IOL implantation in pediatric patients with anterior PFV, with favorable postoperative visual outcomes and compatible percentage of complications.展开更多

All patients were u-nilateral gluacoma , which developed within 1 month following the IOL implantation in 10 cases, and from 1 to 3 years in 4 cases. The angle of anterior chamber was open in 8 patients, and close in 6 ones. Seven patients required treatment of antiglaucomatous medicine; 4 patients underwent laser indecto-my and 3 patients required antiglaucoma surgery. The results s...展开更多

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展开更多

The outcome measure was the presence or absence of post-cataract surgery glaucoma, defined as an intraocular pressure (IOP) ≥26mmHg, as measured on at least two occasions along with corneal or optic nerve changes.RESULTS: The mean follow-up periods of group 1 and 2 were (60.86 ±30.95) months (12-123 months) and (62.11±31.29) months (14-115 months) respectively. In group 1, 12 eyes of 8 patients (4.8% ) developed glaucoma. None of the patients developed glaucoma after surgery in group 2. The mean age of the patients at the cataract surgery was (2.58±0.90) months (1 month-4 months) and the average period for glaucoma development after surgery was (9.50 ±4.33) months (4-16 months) in group 1. Three of the 12 glaucomatous eyes were controlled with antiglaucomatous medication and 9 eyes underwent trabeculectomy+mitomycinC surgery.Onepatientunderwent a second trabeculectomy+mitomycin C operation for both of his eyes.CONCLUSION:The incidence of glaucoma after pediatric cataract surgery is very low in patients in whom IOL is implanted. The aphakic eyes after pediatric cataract surgery are at an increased risk for glaucoma development particularly if they underwent surgery before 4 months of age.展开更多
