Objectives: The study aimed to compare stereopsis, aniseikonia, and associated symptoms in bilateral pseudophakia with and without anisometropia. Methods: Patients with senile cataracts, previously scheduled for phacoemulsification with an IOL implant in both eyes were included in this cross-sectional study. Patients were divided into two groups: control group (n = 69) with an interocular post-surgical refraction difference in Spherical Equivalent (SE) ?;Stereotest. Ten symptoms related to aniseikonia were evaluated with a questionnaire. Statistical evaluation of data included models of univariate, multivariate, and regression analyses. Results: Cataract surgery-induced aniseikonia was 0.64% ± 1.41% in control group and 0.62% ± 1.76% in anisometropia group with an insignificant difference (p = 0.766). Measured stereoacuity was 1.95 ± 0.17 log10 seconds of arc in the control group and 2.12 ± 0.22 log10 seconds of arc in the anisometropia group with a significant difference (p Conclusions: The study showed that stereopsis, aniseikonia, and associated symptoms did not stand for a substantial problem for visual comfort of bilateral pseu- dophakia with anisometropia less than 3D.

OBJECTIVE:To evaluate the distance vision of Chinese patients with cataracts and corneal astigmatism after implantation of bilateral AcrySof toric intraocular lens (IOL) versus bilateral AcrySof spherical IOL.;METHODS:This study randomized 60 patients into equal groups to receive toric IOL or spherical IOL. IOL powers targeting emmetropia were selected for 93% of toric IOL patients and for 90% of spherical IOL patients. Assessments included monocular and binocular distance vision, with and without best correction. Patients also completed surveys about their distance vision.;RESULTS:Preoperatively, the two study groups were similar in age, in distance visual acuity, and in the magnitude of corneal astigmatism. At 6 months postoperative, binocular uncorrected distance vision was 0.06±0.14 logMAR in the AcrySof toric IOL group, significantly better than the 0.14±0.11 logMAR in the spherical IOL group (P<0.05). For eyes with emmetropia as a target, the equivalent of 20/20 uncorrected vision was more likely (P<0.001) in the toric IOL group (36% of eyes) than in the spherical IOL group (4% of eyes). No patients in the emmetropia/toric IOL group used distance glasses, as compared to 52% of patients in the emmetropia/spherical IOL group. All patients were satisfied or highly satisfied. Quality of distance vision was rated higher by toric IOL patients than by spherical IOL patients (P<0.05).;CONCLUSIONS:Bilateral AcrySof toric IOL is superior to bilateral spherical IOL in providing uncorrected distance vision to cataract patients with corneal astigmatism.

AIM: To evaluate a modified technique for scleral buckling(SB) in pseudophakic retinal detachment(RD).METHODS: A retrospective non-comparative study included 21 consecutive eyes with uncomplicated pseudophakic RD that was repaired by chandelier assisted SB using wide angle viewing(WAV) contact lens. Segmental tire alone was used in 5 eyes(23.81%), and combined with encircling band in 7 eyes(33.33%). Radial sponge alone was used in 3 eyes(14.29%) and combined with encircling band in 6 eyes(28.57%).RESULTS: Primary success rate was(90.48%). External drainage of subretinal fluid was performed in 8 eyes(38.1%). Intraoperative complications included vitreous prolapse at chandelier sclerotomy site in 4 eyes(19.05%) and localized subretinal hemorrhage at drainage site in one eye(4.76%). No case of intraocular lens(IOL) displacement, retinal incarceration or iatrogenic retinal tear was detected. Postoperative complications included choroidal detachment in one eye(4.76%), elevated intraocular pressure in 2 eyes(9.52%), epiretinal membrane formation in one eye(4.76%) and proliferative vitreoretinopathy in 3 eyes(14.29%). Mean postoperative corrected distance visual acuity was 0.7±0.3 logMAR units. CONCLUSION: Chandelier-assisted SB using WAV contact lens is a reliable technique for repairing selected cases of simple pseudophakic RD.

AIM: To study the potential reasons of increased straylight in pseudophakic eyes. METHODS: Cross -sectional study. Seventy patients diagnosed as bilateral age-related cataract and implanted with Tecnis ZA9003, Sensar AR40e, SA6OAT, XLSTABI ZO or Akeros AO intraocular lens (IOL) were enrolled in this research. Straylight was measured by a C -Quant straylight meter three to four weeks postoperatively. Five different modalities of IOL, including spherical/aspherical optics and hydrophobic/hydrophilic material were tested in this study. Normal as well as dilated pupils were used. The main outcome variable for straylight measurement was the logarithmic straylight parameter, log(s). RESULTS: The straylight parameter increased significantly after pupil dilation (P<0.05). Straylight of aspherical IOL was significantly higher after pupil dilation (P<0.06) compared to spherical IOL. In normal pupil, straylight of hydrophobic IOL was significant higher when compared with hydrophilic IOL (P<0.05). CONCLUSION: Straylight and visual acuity stand for the different aspects of visual function. Several factors including pupil diameter, optic material, aspherical design of IOL influence intraocular light scattering in pseudophakic eyes. Further investigation was needed to study the impact of optic material and optic surface design on pseudophakic straylight.

AIM:To evaluate the effect of silicone oil removal(SOR) on central corneal thickness(CCT) in aphakic and pseudophakic eyes prospectively.· METHODS:Patients who underwent SOR surgery between June 2005-August 2007 were included in this study.Silicon oil was actively removed behind the posterior capsule through the pars plana sclerotomy site(posterior approach) in pseudophakic eyes and through the pupil and the corneal tunnel incision(anterior approach) in aphakic eyes with the 18-gauge cannula.CCT was assessed with Orbscan II corneal topography system preoperatively and at one month and three months postoperatively.A total of 34 eyes of 34 patients(26 males,8 females) comprised the study group.Mean age was(55.6±12.3) years(Range:25-80 years).Twenty-six eyes(76.5%) were pseudophakic and 8(23.5%) aphakic.Mean time between silicone oil injection and removal was(15.1±13.6) months(Range:5-54 months).At baseline,CCT was 576.4±46.0μm in pseudophakic eyes and 611.6±36.2μm in aphakic eyes.· RESULTS:At the first postoperative month CCT was(573.3±40.1)μm and(630.9±72.9)μm in pseudophakic and aphakic eyes respectively.At the third postoperative month,CCT was(582.7±49.5)μm and(614.5±82.4)μm in pseudophakic and aphakic eyes respectively.There was no statistically significant difference in CCT measurements one month and 3 months after SOR when compared to preoperative values in both aphakic and pseudophakic eyes(P> 0.05).· CONCLUSION:Active SOR either by anterior or posterior approach did not affect the CCT.·

PSEUDOPHAKIC malignant glaucoma is diagnosedbased on the presence of a shallow or flat centraland peripheral anterior chamber in the presenceof patent iridectomy, with intraocular pressure（IOP） of 22 mm Hg or more after lens extraction andintraocular lens implantation.1 Pseudophakic malignantglaucoma is one of the most challenging complicationsfaced by surgeons. Initial medication includes topicalcycloplegics, osmotic agents.

Conductive Keratoplasty for Symptomatic Presbyopia Following Monofocal Intraocular Lens Implantation

2011年浙江省眼科学术会议

We reported the surgical correction with conductive keratoplasty(CK) for 3 cases of residual hyperopia with/without astigmatism after previous laser in situ keratomileusis(LASIK) for high myopia and following phacoemulsification combined with posterior intraocular lens implantation for complicated cataract.Following-up (1-3 years) results showed that the mean logMAR scores of the uncorrected distance and near visual acuity were improved and the manifest refraction spherical equivalent was reduced in all the 3 cases after CK treatment. No sight-threatening complications occurred during the follow-up period.We conclude that CK is an effective and safe treatment for the correction of residual hyperopia in post-LASIK pseudophakia.However,the refractive regression should be considered and the predictive algorithms should be modified.
