    Abstract:

    AIM:Toevaluate factors influencing stereoacuity after surgery to correct unilateral developmental pediatric cataracts.METHODS:We retrospectively surveyed110 patients who had undergone removal of unilateral acquired developmental cataracts and primary posterior chamber intraocular lens implantation between February 1992 and December 2009. In all patients, stereoacuity was assessed using the Titmus test at the last follow-up period of minimum 2 years after surgery. Patients were divided into two groups according to the extent of stereoacuity:group 1 (n=42) had stereoacuity values≤100sec/arc and group 2 (n=68) values >100sec/arc. The values of ten parameters associated with stereoacuity were measured in each group:Cataract types, preoperative best corrected visual acuity (BCVA) of the affected eyes, preoperative inter-ocular difference of BCVA, age at cataract surgery, operative method, secondary cataract, postoperative strabismus, postoperative BCVA of the affected eyes, postoperative inter-ocular difference of BCVA, and anisometropia.RESULTS:The extent of stereoacuity was significantly associated with both operative method and secondary cataract (P=0.000 and P=0.016, respectively). All patients in whom the posterior capsule was preserved, had poor stereoacuity >100sec/arc. Significant correlations with the extent of stereoacuity were found with postoperative strabismus (P=0.048), postoperative BCVA of the affected eyes (P=0.002), anisometropia (P=0.034).CONCLUSION:Postoperative stereoacuity was better in patients who underwent either optic capture or anterior vitrectomy after posterior continuous curvilinear capsulorhexis, and who didn’t develop secondary cataracts or strabismus postoperatively. Furthermore, postoperative BCVA of the affected eyes, and anisometropia influenced the stereoacuity of the patients surgically treated for unilateral developmental pediatric cataracts.
