Abstract Details

Purpose:

To evaluate the incidence of posterior capsular wrinkle (PCW), the relationship between PCW and lens capsular diameter, the position of PCW, and the relationship between PCW and deviation of intraocular lens (IOL), in eyes with 2 types of 1-piece IOL.

Setting:

Subjects comprised 155 eyes (71.0±9.6 years) in TECNIS group and 58 eyes (75.0±8.8 years) in AcrySof group that underwent phacoemulsification with 1-piece IOL at Kanazawa Medical University Hospital and Anamizu General Hospital.

Methods:

PCW within 3 mm diameter area of the pupil center was evaluated in retroillumination images, EAS-1000 (NIDEK). The position of PCW was measured in the counterclockwise direction, taking the center line of optic-haptic junctions or toric mark as 0˚. Lens capsular diameter, axial length, WTW (White To White, corneal horizontal diameter), and corneal curvature radius were measured by IOLMaster (ZEISS), and deviation of IOL by EAS-1000.

Results:

PCW in AcrySof group (69.0%) was significantly higher than that in TECNIS group (32.3%) (P<0.001). In TECNIS group, the incidence of PCW was significantly higher in eyes with short axial length and small WTW (P<0.05). PCW tended to be located 62.0±1.3 degrees from the line of optic-haptic junctions in TECNIS group, with no specific trend in AcrySof group. The tilt and decentration of IOL was significantly larger in eyes with PCW in AcrySof group (P<0.05).

Conclusions:

The mechanism of PCW formation differs by IOL. PCW in eyes with TECNIS may denote good fixation of IOL in the capsular bag, and that in eyes with AcrySof may designate risk of IOL deviation caused by adhesion between the IOL and posterior capsule besides the IOL haptics.
