The baseline data (gender, age, laterality, intraocular lens [IOL] status, best-corrected visual acuity, and intraocular pressure [IOP]) and the intra-operative findings (operative procedure, macular status, lens capsule status, extension of the RD, number of retinal breaks, and location of retinal breaks) were recorded. The visual acuity was recorded in Snellen units and converted to logarithm of the minimum an- gle of resolution (logMAR) units for statistical analysis. Each patient underwent a slit lamp biomicroscopy, fundus photography, and Goldmann’s three mirror lens in order to identify retinal breaks at baseline. The duration of time from when the cataract surgery took place to the time at which the RD was diagnosed was recorded as the time of RD evolution. Scleral buckling (SB) or 20-gauge pars plana vitrectomy was performed according to the surgeon’s preference. Vitrectomy combined with SB was considered for total RD, and multiple or unidentified retinal breaks. Statistical analyses were performed using statistical software (SPSS ver. 11.0; SPSS Inc., Chicago, IL, USA). Univariate and multivariate linear regression analyses were undertaken for the dependent variable in each model. Univariate categorical analysis was performed using the two paired t-test, chi-square test, Mann-Whitney U-test, or the Fisher exact test, as appropriate. Data were analyzed via a repeated-measures analysis of variance with a Bonferroni correction. Correlation analyses were conducted via Spearman’s correlation. Statistical significance was set at 0.05 (two-sided) for all of the tests. Results This study comprised 106 eyes of 104 patients (70 males and 34 females), with a mean age of 55.4 ± 16.7 years (range, 20 to 85 years). The time between onset of RD (defined by the onset of early signs and symptoms, including flashes and JW Lim, et al. Pseudophakic Retinal Detachment floaters) and surgery was 15.4 ± 34.7 days (range, 4 to 75 days). The time of RD evolution was 35.8 ± 26.9 months (range, 1 to 120 months). The mean duration of follow-up was 18.0 ± 8.7 months (range, 12 to 60 months). Ten of the eyes (9.4%) have had previous ocular surgery (an anterior vi- trectomy in six eyes, a penetrating keratoplasty in one eye and refractive surgery in two of the eyes). Cataract surgery was performed on 16 eyes in our hospital and surgery was performed on the remaining 90 eyes in an- other hospital. There were no sclera tunnel incisions and no iris-fixated or anterior chamber lenses. A superior incision was made in four of the eyes (3.8%) and 60 eyes (56.5%) had a temporal incision. The incisional approach for 42 of these eyes (39.6%) was ill-defined. The location of the IOL was in the ciliary sulcus in six eyes, scleral fixation in four eyes, and in the bag in the remaining eyes. Univariate analysis did not show any statistically sig- nificant differences between the baseline visual acuity and the following variables: gender; age; laterality; the time of RD evolution; the duration of symptoms; lower IOP; IOL lo- cation; lens capsule status; identification of a retinal break; number of retinal breaks; location of retinal breaks; and type of surgery. A smaller extension of the RD and a macula-on RD had better baseline visual acuity (p = 0.005, p = 0.002). Surgical management In the SB group (14 eyes), ten of the eyes had segmental SB and four of the eyes had encircling with segmental SB. A primary vitrectomy was performed in 56 eyes (52.8%) and a vitrectomy with SB was performed in 36 eyes (33.9%) (Table 1). Intraocular gas tamponade was used for all 92 eyes that un- derwent vitrectomy (20% SF6 [40 eyes] and 14% C3F8 [52 eyes]). There were no cases in which air or silicone oil tampo- Table 1.
