Changes of Preoperative and Postoperative Anterior Chamber Angle in Phacoemulsification and Planned Extracapsular Cataract Extraction

ABSTRACT

To compare the preoperative and postoperative anterior chamber (AC) angle in cataract surgery, we performed phacoemulsification followed by posterior chamber intraocular lens (PCIOLs) implantation with 20 eyes (Group I) and planned extracapsular cataract extraction (p,ECCE) followed by PCIOLs implantation with 20 eyes (Group I). After that, we measured prospectively the preoperative and postoperative AC angle 1, 3, 7, 30 and 60 days by using a Scheimpflug camera. The preoperative mean values of AC angle were 3 1.25 3. 47 in Group I and 30. 58+/-4. 42` in Group I. The mean deepening of the AC angle was 3.24` in Group ! and 3.30` in Group n , the charnber angle quotient. was 1.10 in Group 1 and 1.15 in Group I at the postoperative one day. There was statistically significant difference (P0. 5). Based on these results, the deepening of AC angle after cataract surgery may be considered for cataract. extraction and posterior displacement of PCIOLs due to anterior angulation of PCIOLs haptics.
