Abstract: AlM:To observe the clinical efficacy of two types of scleral-fixated posterior chamber intraocular lens ( lOL ) combined intra-capsule lens extraction to treat cataract dislocation.
METHODS: After intra - capsule lens extraction of dislocated cataract, two types of lOL were used as scleral-fixated posterior chamber lOL . First group was with four seal loops, the second group was with two open loops. All 21 patients (23 eyes) took the examination of the best corrected visual acuity, intraocular pressure, fundus, and lOL decentration using camera system attached to slit - lamp ophthalmoscope and lOL tilted using ultrasound biomicroscopy (UBM) at 6mo after surgery.RESULTS: After 6mo, all patients had improved eye sight. There was significant difference in the mean lOL decentration between the two groups ( 0. 57mm vs 0. 79mm, P<0. 05). There was significant difference in the mean lOL tilted degree between the two groups (6° vs 11°, P<0. 05) .
CONCLUSlON: lOL with four loops are more appropriate as scleral-fixated posterior chamber lOL with less tiltness and dicentration.
