Comparison of clinical results between heparin surface modified hydrophilic acrylic and hydrophobic acrylic intraocular lens 总被引:1,自引:0,他引:1
PURPOSE. To compare the clinical results of heparin surface modified (HSM) hydrophilic acrylic intraocular lens (IOL) with those of hydrophobic acrylic IOL. METHODS. One hundred patients with cataract were randomized to receive one of acrylic foldable IOLs after phacoemulsification: HSM hydrophilic acrylic IOL (n=50) BioVue3(R) (BioVue, OII, Ontario, CA, USA) and hydrophobic acrylic IOL (n=50) Sensar(R) (AR40e, AMO, Santa Ana, CA, USA). Bestcorrected visual acuity and refractive error were measured at 1 week, 2 months, 6 months and 12 months after surgery in both IOL groups. To assess posterior capsular opacification (PCO), digital retroillumination image of posterior capsule was analyzed at 12 months using POCOman software. RESULTS. Best-corrected visual acuity (log MAR) was 0.032+/-0.082 in BioVue3(R) group and 0.034+/-0.077 in Sensar(R) group at 12 months. There was no statistically significant difference between the two groups (p=0.554). Refractive error was -0.247+/-0.821 diopter in BioVue3(R) group and -0.264+/-0.808 diopter in Sensar(R) group at 12 months. There was no statistically significant difference of refractive error between the two groups (p=0.909). At 12 months, BioVue3(R) IOL group had a lower percentage area and severity of PCO than Sensar(R) group. However, it was not statistically significant (p=0.349, p=0.288). No Nd:YAG capsulotomy was performed in BioVue3(R) group while it was required in two eyes (4.0%) in Sensar(R) group. CONCLUSIONS. There was no statistically significant difference of postoperative visual acuity, refractive error and degree of PCO between HSM hydrophilic acrylic IOL and hydrophobic acrylic IOL. 相似文献

Purpose To compare posterior capsular opacification (PCO) in a heparin-surface-modified (HSM) hydrophilic acrylic intraocular lens
(IOL) and a hydrophobic acrylic IOL.
Methods Seventy-eight patients with simple cataract were randomized to receive either the BioVue 3 HSM hydrophilic acrylic IOL (Ophthalmic
Innovations International, Ontario, CA, USA) (n = 38) or the Sensar AR40e hydrophobic acrylic IOL (AMO, Santa Ana, CA, USA) (n = 40). Another 99 patients with complicated cataract received either the BioVue 3 (n = 49) or the Sensar AR40e IOL (n = 50). Twelve months after surgery, POCOman software was used to analyze digital retroillumination photographs of the PCO.
Results In the simple cataract group, the respective PCO areas, expressed as a percentage and PCO severity scores at 12 months were
6.12% and 0.081 in the BioVue 3 group and 5.91% and 0.075 in the Sensar AR40e group. There was no statistically significant
difference in the PCO area or the PCO severity score between the two IOLs (P = 0.631, P = 0.495, respectively). In the complicated cataract group, the respective PCO areas and PCO severity scores were 35.80% and
0.181 in the BioVue 3 group and 27.17% and 0.110 in the Sensar AR40e group. There was no statistically significant difference
between the two IOLs (P = 0.147, P = 0.162).
Conclusion There was no difference in the degree or severity of PCO between the HSM hydrophilic acrylic IOL and the hydrophobic acrylic
IOL groups. 相似文献

AIM:To compare posterior capsule opacification (PCO) degree and visual functions after phacoemulsification in eyes implanted with 360-degree square edge hydrophilic acrylic intraocular lens (IOL) (570C C-flex, Rayner) and sharp edge hydrophobic acrylic IOL (Sensar AR40e, AMO) in diabetic patients.METHODS:Sixty diabetic patients underwent uneventful phacoemulsification and randomly implanted one of the two IOLs. The PCO value was measured by retroillumination photographs and Evaluation of Posterior Capsule Opacification (EPCO) 2000 image-analysis software at 1, 6, 12, and 24mo after surgery. Visual acuity, and contrast sensitivity in photopic and mesopic conditions were also examined at each follow up time point. The incidence of eye that required Nd:YAG laser posterior capsulotomy were also compared.RESULTS:There was not any statistically significant difference in PCO scores between Rayner C-flex 570C group and Sensar AR40e group at each follow up time point. Visual acuity, Nd:YAG capsulotomy incidence and contrast sensitivity also had no significant difference during the 24mo follow-up.CONCLUSION: For diabetic patients, Rayner 570C C-flex and Sensar AR40e IOLs are same effective for prevent PCO. The 360-degree square edge design maybe is a good alternative technique to improve PCO prevention. 相似文献

PURPOSE: To compare the degree of posterior capsule opacification (PCO) and visual function between fellow eyes that received two different types of hydrophobic acrylic intraocular lenses (IOLs). METHODS: Forty-five patients underwent bilateral phacoemulsification and implantation of an Alcon AcrySof IOL (MA60AC) in one eye and an AMO Sensar IOL (AR40e) in the fellow eye. The PCO density value was measured using the Scheimpflug videophotography system at 1, 6, 12, and 24 months after surgery. The incidence of eyes that required a neodymium:YAG (Nd:YAG) laser capsulotomy, visual acuity, and contrast sensitivity with and without a glare source were also examined. RESULTS: The mean PCO value did not show a significant increase in either the AcrySof MA60AC or Sensar AR40e IOL groups, and was similar between the two groups throughout the 24-month follow-up period. The incidence of Nd:YAG laser capsulotomy was also the same between the groups. No significant difference was found in mean visual acuity between the two IOL groups during the follow-up, and there was no significant difference in photopic or mesopic contrast visual acuity with and without a glare source at 1 and 24 months after surgery. Conclusion: The degree of PCO in eyes with an AcrySof IOL are almost the same as that in eyes with a Sensar IOL, with the results that visual acuity and contrast sensitivity with and without glare are similar. 相似文献

Influence of optic edge design and anterior capsule polishing on posterior capsule fibrosis 总被引:3,自引:0,他引:3
Sacu S Menapace R Findl O Georgopoulos M Buehl W Kriechbaum K Rainer G 《Journal of cataract and refractive surgery》2004,30(3):658-662
PURPOSE: To evaluate the role of posterior optic edge design and the effect of anterior capsule polishing on peripheral fibrotic posterior capsule opacification (PCO). SETTING: Department of Ophthalmology, University of Vienna, Vienna, Austria. METHODS: This randomized prospective study comprised 144 eyes of 72 patients with bilateral age-related cataract. Each patient had standardized cataract surgery in both eyes by the same surgeon. Group 1 (46 patients) received a round-edged hydrophobic acrylic IOL (AMO Sensar AR40) in 1 eye and a sharp-edged hydrophobic acrylic IOL (AMO Sensar OptiEdge AR40e) in the other eye. Group 2 (26 patients) received a silicone IOL (Pharmacia CeeOn 911A) with a truncated optic in both eyes. In this group, the anterior capsule was extensively polished in 1 eye and was left unpolished in the other eye. Digital slitlamp photographs were taken 1 year postoperatively using a standardized photographic technique for fibrotic PCO. The intensity of PCO was subjectively graded (score 0 to 4) by 2 masked examiners. RESULTS: Subjective PCO scores correlated well between the 2 examiners (r = 0.88). In Group 1, the mean PCO score was 0.26 for the OptiEdge AR40e IOL and 0.90 for the AR40 IOL (P<.01). In Group 2, the mean PCO score was 0.24 in eyes with a polished capsule and 0.17 in eyes in which the capsule was not polished (P =.31). CONCLUSIONS: The sharp-edged OptiEdge AR40e IOL led to significantly less peripheral fibrotic PCO 1 year postoperatively than the round-edged AR40 IOL. In eyes with the sharp-edged silicone 911A IOL, anterior capsule polishing caused no significant difference in fibrotic PCO. 相似文献
