Phacoemulsificatıon in eyes wıth cataract and high myopia
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
ABSTRACTPurpose:To evaluate the outcomes and complications following phacoemulsification surgery in eyes with cataract and high myopia.Methods:We retrospectively evaluated the data of 43 eyes of 28 consecutive patients (12 males, 16 females) with cataract and high myopia who had undergone phacoemulsification and intraocular lens (IOL) implantation. The mean [± standard deviation (range)] age of the patients was 59.20 ± 11.08 (39-77) years.Results:The frequency of nuclear cataract was significantly higher than that of other cataract types (P=0.003). The mean axial length was 28.97 ± 1.99 (26-33) mm and the mean IOL power was 5.09 ± 4.78 (-3.0 to +14.0) diopters (D). The mean preoperative spherical equivalent (SE) was -16.48 ± 5.23 (-8.00 to -25.00) D and the mean postoperative SE was -1.46 ± 0.93 (0.00 to -3.00) D (P=0.00). The mean preoperative best-corrected visual acuity (BCVA) was 0.91 ± 0.37 (0.30 to -1.50) logMAR and the mean postoperative BCVA was 0.29 ± 0.25 (0.00-1.00) logMAR (P=0.00). Twenty-two eyes (51.2%) achieved the target postoperative refraction (±1.0 D). The eyes were divided into 3 groups according to the axial length. The mean biometric error was significantly higher in the group with the greatest axial length than in the other groups (P=0.007). Preoperative argon laser photocoagulation was performed in 7 eyes (16%) on account of retinal tears, retinal holes, or lattice degeneration. Postoperatively, retinal tears developed in 2 eyes (4%) and were treated with photocoagulation. One eye (2%) developed retinal detachment postoperatively, with the patient consequently referred for retinal surgery. Postoperatively, posterior capsule opacities developed in 11 eyes (25%), with all cases treated by laser capsulotomy.Conclusions:Good postoperative outcomes following phacoemulsification surgery were observed in patients with cataract and high myopia. However, clinicians should be aware of the risk of postoperative retinal tears and rhegmatogenous retinal detachment. Preoperative prophylactic argon laser photocoagulation treatment should be considered where necessary.
