ABSTRACT
Purpose@#To assess the refractive changes and stability after cataract surgery with insertion of three different intraocular lenses in axial myopes. @*Methods@#A retrospective analysis was performed with 44 eyes of normal axial length (22.0 mm < axial length ≤ 24.5 mm) and 49 eyes of long axial length (24.5 mm < axial length) in patients who underwent phacoemulsification and posterior chamber lens insertion. Automated keratometry examination and refraction were performed using an autorefractor keratometer; A-scan ultrasound was used to calculate target refraction. One-piece intraocular lenses (IOLs) and three-piece IOLs were inserted. At 2 and 12 months postoperatively, refraction differences relative to the target refraction (calculated using the SRK-T formula) were analyzed. The refractive changes between 2 and 12 months postoperatively were compared according to the IOL. @*Results@#Myopic shift from the target refraction was observed with eyes of long axial length, compared with eyes of normal axial length, at 2 and 12 months postoperatively (p = 0.003, p = 0.013). For refractive stability according to IOL, there was no significant difference in eyes with normal axial length; in eyes with long axial length, three-piece IOLs showed significant refractive stability (p < 0.05). @*Conclusions@#In eyes with long axial length, there was a significant difference in postoperative refractive stability according to the inserted IOL; three-piece IOLs showed significant refractive stability compared with one-piece IOLs.
