“…In the present study, IOL materials were either hydrophobic or hydrophilic. Previous studies have reported that the incidence of PCO in patients implanted with hydrophilic lenses is higher than the in patients implanted with hydrophobic lenses [ 24 ]. However, some studies have reported that the incidence of PCO using hydrophilic lenses is less than in patients using hydrophobic lenses [ 25 , 26 ].…”

Purpose To evaluate the potential risk factors of posterior capsule opacification (PCO) after cataract surgery. Methods Data on PCO patients diagnosed from September 2015 to May 2017 were obtained from the Department of Ophthalmology at Qingdao Municipal Hospital, Qingdao, China. The factors associated with PCO were assessed using Pearson's χ2 test for univariate analyses and logistic regression for multivariate analyses. Results Eyes (652) from 550 patients were enrolled in this study. All patients were diagnosed with PCO/non-PCO and had <3 years of follow-up after surgery. The numbers of PCO and non-PCO were 108 eyes and 544 eyes, respectively. Statistically significant associations with PCO were found for age at the time of surgery (χ2 = 78.504; p < 0.001), diabetes (χ2 = 4.829; p=0.028), immune diseases (χ2 = 4.234; p=0.004), high myopia (χ2 = 5.753; p=0.016), lens nucleus hardness (χ2 = 11.046; p=0.026), surgery type (χ2 = 11.354; p=0.001), a history of vitrectomy (χ2 = 4.212; p=0.004), ocular inflammation (χ2 = 6.01; p=0.009), and the intraocular lens (IOL) type (χ2 = 8.696; p=0.003). Multivariable data analyses using logistic regression analyses of the variables showed that age at the time of surgery <60 years, diabetes, lens nucleus hardness of III–V, extracapsular cataract extraction (ECCE), postvitrectomy, and hydrophilic IOLs were significant independent risk factors associated with PCO. Conclusions Age <60 years, diabetes, lens nucleus hardness of III–V, ECCE, postvitrectomy, and a hydrophilic IOL were significantly associated with the formation of PCO. Estimation of the incidence of and risk factors for PCO should help in patients counseling and in the design of treatment protocols to reduce or prevent its development.

“…In previous studies about Nd:YAG capsulotomy rates evaluation showed hydrophilic lenses had statistically higher Nd:YAG capsulotomy rates than hydrophobic lenses. 4,16,17 In this study, although there are slight differences in the design of the two kinds of multifocal IOLs, their optical configurations are dihedral aspheric surface with square edges, the multifocal design is located on the front surface, the back surface is aspheric, and the haptic angulation is 0°. In terms of materials, both are hydrophilic multifocal IOLs, but diffractive MIOL has a hydrophobic surface.…”

Purpose:To investigate the incidence of Nd:YAG capsulotomy after implantation of two types of multifocal intraocular lenses (MIOLs). Methods: This retrospective analysis included patients who had undergone cataract extraction and implanted diffractive MIOL (Acri. LISA tri 839M) or asymmetric refractive MIOL (SBL-3) from May 2016 to September 2018. They were followed up for at least 3 years. During the followup period, the relevant data of patients were kept by special person in the hospital. The rates of Nd: YAG capsulotomy and the Kaplan-Meier survival curve were used to analyze the two groups. Results: The Asymmetric Refractive MIOL group was comprised of 98 patients (121 eyes), while the Diffractive MIOL group was comprised of 99 patients (120 eyes). There were no significant differences in age, sex, or IOL power between the two groups. The Nd:YAG rate of the asymmetric refractive MIOL group and the diffractive MIOL group was 3.3% and 7.5% respectively (P = 0.15) in the first year, 14.88% and 22.5% respectively (P = 0.129) in the second year, and 21.49% and 34.17% respectively (P = 0.028) in the third year. In the first 7 months of follow-up, the two groups showed the same performance in the Nd:YAG rate. After that, there was a difference between the two groups, and the difference gradually increased. Until the 27th month of follow-up, the difference was significant (P < 0.05). What is more, there were significant differences in survival (without Nd:YAG capsulotomy)/failure (with Nd:YAG capsulotomy) functions (P = 0.0035). Conclusion:The incidence of Nd:YAG laser capsulotomy in patients with diffractive MIOLs was higher than that in patients with asymmetric refractive MIOLs.

“…Acrylic material is associated with reduced PCO rate by causing a lower postoperative inflammation than the previously used materials [9]. In addition, lenses with sharp edge design have better outcomes by the inhibition of lens epithelial cells' (LECs) migration [16].…”

Introduction/Objective The most frequent postoperative complication of a successfully performed phacoemulsification cataract surgery is the development of posterior capsule opacification (PCO). It is caused by the proliferation and migration of the remaining residual epithelial cells. The objective of this study was to investigate the influence of two different intraocular lenses and two different anti-inflammatory drugs on the development of PCO in one-year follow-up period. Methods Investigation included 120 patients (120 eyes), equally divided into four groups. The first two groups included patients who used non-steroid anti-inflammatory drug (NSAID) postoperatively, while the other groups had corticosteroid therapy. The first and third group got hydrophilic intraocular lenses (IOL), the second and fourth group had hydrophobic IOL. Software program EPCO 2000 was used for the analysis of PCO. Student's t-test, Wilcoxon test, and ANOVA were used for data analysis and p < 0.05 value was accepted as statistically significant. Results After the first three postoperative months, patients from NSAID groups had mean PCO score 0.25 ± 0.03, which was statistically significant higher (p = 0.042) comparing to corticosteroid groups. At the end of the investigation, the best result in PCO preventing was seen in the group of patients with hydrophobic IOL and corticosteroid therapy, with the mean PCO score of 0.47 ± 0.08. Conclusion This study has revealed that IOL made of acrylic hydrophobic material seemed to be the right choice when choosing intraocular lens to prevent PCO development. On the other hand, NSAID and corticosteroid therapy have showed similar results in preventing postoperative intraocular inflammation. This fact can be very useful in situations when corticosteroids must be used with great caution.
