| Background And BurposePhacoemulsification with intraocular lens implantation in the conduct of the patients have been safe, clear and comfortable visual effects.However, posterior capsular opacification after cataract surgery (posterior capsular opacificiation PCO), still lead to long-term vision has dropped by another one of the most important factor.How to be safe and effective in preventing the occurrence of cataract is the domestic and foreign scholars have been pursuing the goal.With the widespread application of modern microsurgery, the continuous improvement of the quality of the continuous improvement of surgical techniques and intraocular lens increased and has greatly improved the visual acuity of cataract patients But has not yet fundamentally eliminate the occurrence of PCO. One of the intraocular lens optical zone material after cataract incidence is also a hot research.Here, we retrospectively analyzed two different materials of foldable intraocular lens implantation of posterior capsule opacification, intraocular lens for the clinical selection of safe and effective to provide a basis for reference should be madeMaterials and Methods Sucked out from May2008to May2010in the hospital phacoemulsification cataract and intraocular lens implantation in elderly patients62cases (72eyes),35males (35eyes) and27females (37eyes), age between49and79years old, mean age (68.5±6.5) years of age.The retrospective analysis were randomly divided into group A and group B, the two groups, each group divided into three age groups by age (49～58) of group A, group B (59～68) years of age, group C (69to79) years of age12people each.A group of implantation of the Alcon company of Acrysof SA60AT hydrophobic acrylic foldable intraocular lens of the material, and another set of foldable intraocular lens implantation Japan the Canon staar silicone gel material.By the same surgeon, the surgery done under local anesthesia, phacoemulsification combined with intraocular lens in the capsular bag implantation.After1week,1month,6months,12months,24months observed in patients with best corrected distance visual acuity, best corrected near vision inflammation, and be followed up regularly.Evaluation in accordance with the sellman and lindstom slit lamp examination of posterior capsule opacification grading method records, simultaneous recording of eye surgery, best corrected distance vision, near vision,SPSS17.0statistical software for statistical analysis of the data, visual acuity results using independent samples t test, posterior capsule opacification using the X2test, inspection level a=0.05.ResultsAlcon lens group A age and age of Japan’s Canon lens group A compared to1week after surgery best corrected distance vision,(t=0.60, P=0.54>0.05) no significant.Alcon lens group B ages and Japan’s Canon lens group B after age compared to one week of best corrected distance visual acuity (t=0.43, P=0.66>0.05) difference not statistically significant.Alcon lens group C ages and the age of Japan’s Canon lens group C one week after best corrected distance visual acuity compared to (t=0.39, P=0.75>0.05) were no significant differences.Alcon lens group A age and age of Japan’s Canon lens group A after12months the best corrected distance vision compared to (t=1.31, P=0.02<0.05) difference was statistically significant.Alcon lens group B ages and Japan’s Canon lens group B age 12months, Alcon lens group C ages, and Japan’s Canon lens group C age after12months the best corrected distance visual acuity compared to P<0.05was considered statistically significant.Can draw two different ages of patients with senile cataract phacoemulsification in addition to surgery and intraocular lens implantation Alcon lens group12months in patients with best corrected distance vision than Japan’s Canon lens patients12The corrected distance visual acuity P <0.05was statistically significant.Two groups of cataract patients after implantation of two different after intraocular lens capsule opacification different Alcon posterior capsule opacification in the lens group8.3%of the three eyes, posterior capsule opacification in the Canon lens group in Japan9eyes25.0%difference was statistically significant (X2=4.056p=0.021<0.05),Alcon lens group and Japan’s Canon lens group in the implantation of different intraocular lens12months after capsulotomy were not appear three, four, posterior capsule opacification.It can be seen two different intraocular lens implantation12months after capsular opacification.ConclusionsPhacoemulsification cataract extraction with intraocular lens implantation in the group of acrysof the hydrophobic SA60AT acrylic material foldable intraocular lens has a lower incidence of posterior capsule opacification compared to the group of acrylic material foldable intraocular lens decreased vision slowly... |
