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.

Abstract
Purpose: To compare the stability of intraocular lens (IOL) insertion methods of sutured haptics in the bag with scleral fixation to those of in the bag insertion and scleral sulcus fixation. Methods: In group of only phacodonesis, two IOL insertion methods, in the bag insertion and sutured haptics in the bag with scleral fixation were compared. In group of phacodonesis with less than 90° zonulysis, two IOL insertion methods, sutured haptics in the bag with scleral fixation and scleral sulcus fixation were compared. Postoperative 2 months and 12 months refraction were compared with target refraction and the refractive change between postoperative 2 and 12 months were compared in each group. The change of anterior chamber depth (ACD) at postoperative 2 and 12 months were compared with preoperative ACD, and the change of ACD between postoperative 2 and 12 months were compared in each group. Results: In group of only phacodonesis, the typical in the bag insertion group showed significant ACD change between postoperative 2 and 12 months (<i>p</i> = 0.010), but the group of sutured haptics in the bag with scleral fixation didn’t show the significant ACD change (<i>p</i> = 0.515). In group of phacodonesis with less than 90° zonulysis, the sulcus scleral fixation method showed significant ACD change and significant refractive change (<i>p</i> = 0.015, <i>p</i> = 0.004), but the group of sutured haptics in the bag with scleral fixation method didn’t show the significant ACD nor refractive change (<i>p</i> = 0.713, <i>p</i> = 0.106) between postoperative 2 and 12 months. Conclusions: In eyes with zonular instability, sutured haptics in the bag with scleral fixation method can promote the postoperative stability of IOL.
