Anterior chamber depth with sulcus and capsular bag placed IOGEL lenses.

Abstract:

:The anterior chamber depth was measured in 15 eyes with sulcus placed (Group 1) and 12 eyes with bag placed (Group 2) IOGEL PC-12 lenses, and in 11 eyes with bag placed IOGEL 1103 lenses (Group 3). The mean anterior chamber depth was 3.29 mm in Group 1, 4.17 mm in Group 2, and 4.16 mm in Group 3. The difference between the mean anterior chamber depth with sulcus and bag placed IOGEL PC-12 lenses is statistically significant (P less than .0005). One effect of the different anterior chamber depths was that the anterior surface of a sulcus placed IOGEL lens frequently touched the pupillary border, whereas this rarely occurred when it was placed in the capsular bag. Another effect of differing anterior chamber depths was a different A-constant for the SRK-formula for sulcus or bag placement. In this study it was about 1 diopter greater with bag fixation than with sulcus fixation. It is recommended that each surgeon use specific A-constants to enhance the predictability of the postoperative refraction.
