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 (p = 0.010), but the group of sutured haptics in the bag with scleral fixation didn’t show the significant ACD change (p = 0.515). In group of phacodonesis with less than 90° zonulysis, the sulcus scleral fixation method showed significant ACD change and significant refractive change (p = 0.015, p = 0.004), but the group of sutured haptics in the bag with scleral fixation method didn’t show the significant ACD nor refractive change (p = 0.713, p = 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.
