RESUMEN
AIM: To compare the effect of treating cataract by sodium hyaluronate injection and lens - loop nucleus extraction of small incision cataract excision and explore more suitable method to promote the use of surgery in primary hospital. METHODS: All 146 cataract patients ( 166 eyes ) were allocated to two groups in random: the control group 78 patients ( 84 eyes ) received conventional lens loop for extracapsular cataract extraction;the experiment group 68 patients (82 eyes) underwent nucleus extraction in small incision with sodium hyaluronate injection for extracapsular cataract extraction. Postoperative visual acuity and intraoperative and postoperative complications were compared between two groups. RESULTS: Incidence of posterior capsule rupture difference was statistically significant (P 0. 05 ) in postoperative visual acuity, astigmatism degree and postoperative complications compared with those of pre-operation. CONCLUSION: Compared with the lens loop nucleus extraction, sodium hyaluronate injection for extracapsular cataract extraction can effectively protect the posterior lens capsule and can be promoted in small incision cataract surgery.
RESUMEN
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 CONCLUSlON: lOL with four loops are more appropriate as scleral-fixated posterior chamber lOL with less tiltness and dicentration.
