Clinical observation of ciliary sulcus fixation of posterior chamber intraocular lens in aphakic eyes / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To explore the clinical efficacy of ciliary sulcus fixation of posterior chamber intraocular lens(IOL)in aphakic eyes with inadequate capsule support. <p>METHODS: A retrospective review of medical records of 38 eyes of 38 patients who were underwent ciliary sulcus fixation of posterior chamber IOL from 2015 to 2018 were analyzed for the intraoperative and postoperative complications, intraocular pressure and position of intraocular lens. Also, the preoperative and postoperative visual acuity and refractive status were compared respectively. The follow-up time was 3mo after surgery. <p>RESULTS:The intraoperative hyphema occurred in 6 eyes(16%)postoperative hypotony in 4 eyes(11%)transient high intraocular pressure in 11 eyes(29%), yet all were cured by treatment. Four eyes(11%)with obvious tilt of intraocular lens were observed. All the cases were an visual improvement according to the last postoperative follow-up(<i>P</i><0.05). No obvious difference between target refraction(spherical lens)and actual refraction(spherical lens)at postoperative 3mo was discovered(<i>P</i>>0.05).<p>CONCLUSION: The ciliary sulcus fixation of posterior chamber IOL is a safe and effective way to treat the aphakic eyes, but the possible complications should be attentional.

Iris-claw intraocular lens implantation after pupil re construction for aphakic eyes caused by ocular trauma / 眼科新进展

Objective To observe the effect of implantation of iris-claw intraocu lax lens combined with pupil reconstruction on aphakic eyes caused by ocular trauma.Methods The clinical data of 17 patients (17 eyes) of aphakic eyes treated with irisclaw intraocular lens implantation and pupil reconstruction were analyzed retrospectively,and the visual acuity,corneal endothelial cell count,intraocular pressure,intraocular lens location,pupil condition and postoperative complications were observed.Results Intraocular lens were implanted and pupils were repaired in all 17 patients (17 eyes) successfully,with no complications of intraocular lens dislocation and corneal decom pensation.The postoperative uncorrected visual acuity (0.52 + 0.17) was better than the preoperative visual acuity (0.04 + 0.02) and preoperative best corrected visual acui ty (0.44 +0.13).The corneal endothelial cell count was (1993.88 + 127.24) mm-2 6 months after operation,which was lower than that of preoperative date (2178.88 + 132.61)mm-2 (P ＜ 0.05).Preoperative intraocular pressure (15.91 + 2.73) mmHg (1 kPa =7.5 mmHg) was not significantly different from postoperative intraocular pressure (16.69 + 2.61) mmHg (1 kPa =7.5 mmHg) (P ＞ 0.05).The postoperative pupil size [(4.4 + 0.2) mm] was smaller than that of preoperative date [(5.5 + 0.3) mm] (P ＜ 0.05).The symptoms of photophobia,glare and diplopia did not occur postoperatively.Conelusion Pupil reconstruction combined with iris-claw intraocular lens implanta tion is a safe and effective method for aphalic eyes combined with absence of capsule support and ruptured iris.

Analysis of application of rigid gas permeable lens in aphakic patients / 国际眼科杂志(Guoji Yanke Zazhi)

?AIM:To compare the corrected vision and improvement of visual quality after wearing rigid gas permeable corneal lens ( RGPCL) or spectacles in aphakic patients.?METHODS: We selected 29 aphakic patients ( 29 eyes ) caused by different reasons wearing RGPCL and spectacle.The corrected vision, eye condition and visual quality were observed and all patients were followed up for 6mo.? RESULTS: RGPCL was better than spectacle on corrected vision (P<0.05).The patients who wore RGPCL for long had no corneal complications reported. The patients who wore RGPCL had better subjective visual quality than those wore spectacle.?CONCLUSION: RGPCL is a good choice for correcting high myopia and astigmatism for aphakic patients.The patients'compliance is good. Wearing RGPL long has high safety for patients'ocular surface.

Q-Switched Nd:YAG laser Posterior Capsulotomy of the Aphakia and Pseudophakia Inserted with Posterior Chamber IOL

To get the pure clinical results of Yag Laser Posterior Capsulotomy, excluding all the possible factors that might affect the results of that, we performed posterior capsulotomies on after cataracts(118 eyes) by using Q-switched Nd:Yag laser from February 1987 to August 1989 and reviewed the results. Group A is composed of 68 surgical aphakic eyes and group B is composed of 50 Posterior chamber pseudophakic eyes. The results were as follows: 1. One eye in groupA and one eye in group B were congenital cataracts and the others were all adult and senile cataracts. 2. As a result of posterior capsulotomy, 59 eyes(86.8%) in group A and 42(84%) in group B were above 0.5 in corrected visual acuity. 3. On performing, the power setting was under 1.5mJ in 59 eyes(86.8%) in groupA and 40 eyes(80%) in group B. 4. Ocular complications developed in 35 eyes(51.5%) in group A and 15 eyes(30%) in group B. 5. Good preoperative ocular condition may predict good postoperative clinical results. 6. Less energy and pulses in operation combined with less occurrences of vitrous prolapse in group B might be associated with less development of postoperative complications in group B than in group A.

Apparent accommodation in monocular pseudophakic eyes and contact lens wearing monocular aphakic eyes

To investigate the presence of apparent accommodation in monocular pseudopakic eyes and contact lens wearing monocular aphakic eyes, we measured it in 54 monocular pseudophakic eyes (54 patients) and 40 contact lens wearing monocular aphakic eyes (40 patients). The mean apparent accommodation was 1.68+/-1.25 diopters in monocular pseudophakic eyes and 1.74+/-0.73 diopters in contact lens wearing monocular aphakic eyes, and there was no statistically significant difference between them. Apparent accommodation was not related either to type of intraocular lenses or pupil size in pseudophakic eyes and not related to target size in aphakic eyes, but it was influenced by pupil size in aphakic eyes. In the group of patients aged between 45 and 55, accommodation in phakic eyes was significantly greater than apparent accommodation in contralateral contact lens wearing monocular aphakic eyes.
