ABSTRACT
Objective: To analyze the changes in visual function and adverse effects of wearing rigid gas permeable contact lens (RGPCL) and primary intraocular lens (IOL) implantation in the infants with monocular aphakia after congenital cataract surgery. Methods: The pre- and postoperative visual acuity, strabismus, nystagmus, adherence to patching and adverse events of the patients with unilateral congenital cataract who underwent cataract surgery with or without primary IOL implantation were analyzed retrospectively. RGPCLs were used to correct aphakia who did not receive IOLs. Results: All of 60 patients were included in this study. Twenty patients with unilateral aphakia used RGPCLs (group 1). Forty patients were implanted with IOLs primarily (group 2). In group 1, there was obvious improvement in visual acuity and strabismus (P<0.05). There was no statistic difference in visual acuity and strabismus between group 1 and group 2 finally. Nystagmus remission rate in group 1 was higher than that in group 2. The patients with adherence to patching had better visual acuity after operation than those without (P<0.05). All of the patients in group 1 had no ocular disease that affect visual acuity. More adverse events happened in group 2. Conclusion: Wearing RGPCL is a safe and effective optical correction method for the patients with monocular aphakia after congenital cataract surgery, especially for the patients below 2 years old who are not suitable for IOL implantation. RGPCL has similar visual correction effect on the patients with primary IOL implantation, but it is accompanied by less adverse events.
ABSTRACT
Objective To observe the effect of comprehensive treatment in children with severe amblyopia.Methods One hundred and forty children(140 eyes)with severe amblyopia aged 5-14 were divided into two groups.The patients in both groups received cover method,drug suppression method, fine cross training.Patients in experimental group received the treatment of wearing rigid gas permeable contact len(RGPCL)combined with machine instrument training and patients in control group received the treatment of wearing suitable frame mirror. They were followed up for 18 months. Results After treatment of 18 months,the total effective rate in experimental group was significantly better than that in control group:100.0%(68/68)vs. 80.6%(58/72),P < 0.01. Before treatment,the three-level visual function rate in two groups had no significant difference(P > 0.05). After 3 months'training with the visual machine,the three-level visual function rate in experimental group was significantly higher than that in control group: 80.9%(55/68)vs. 63.9%(46/72),P < 0.05. Conclusions Active amblyopia treatment is effective and the two sides should cooperate effectively.The patients with severe amblyopia who receive wearing RGPCL combined with machine instrument training treatment is better than those of wearing frame mirror and the safety and efficacy is guaranteed.
