AIM: To observe the clinical effects of the sutureless intraocular suspended implantation of foldable three-piece acrylic aspheric posterior chamber lens ( Tecnis ) through clear corneal incision. METHODS:A total of 21 patients (24 eyes) with non or unintact capsule that underwent the intraocular suspended implantation of foldable three-piece acrylic aspheric posterior chamber lens ( Tecnis ) through clear corneal incision were observed and compared clinically to evaluate the clinical effects of this operative method. The observation and comparison were made on the parameters including visual acuity, intraocular reaction and lens situation by ultrasound biomicrography ( UBM) before and after the operation. RESULTS:A 3-12 months (6.5 months on average) follow up shows significant improvement ( P<0.01 ) of both the uncorrected and corrected visual acuity of 24 eyes.The corrected postoperative visual acuity were 1.0-1.5 (8 eyes, 33.3%), 0.5-0.9 (13 eyes, 54.2%) and 0.1-0.4 ( 3 eyes, 12.5%), respectively. There was no statistical difference in the distance from the plane of artificial lens body to corneal endothelium, and the distance from ciliary process to corneal endothelia ( P>0.05) in UBM photos after operations.All of 24 eyes were successfully conducted intraocular lens implantation without serious, intraocular infections or inflammations, no complications like cyclodialysis or retinal detachment.Only a few cases present temporary increase of intraocular pressure. CONCLUSION: The sutureless intraocular suspended implantation of foldable three-piece acrylic aspheric posterior chamber lens ( Tecnis ) through 3.0-6.0mm clear corneal incision is an advisable remedy for capsule rupture failure during phaco -emulsification and an advisable operation for the dislocation of crystalline lens resulted from trauma or congenital cataract. The procedure can improve visual acuity safely and effectively without obvious complications.Its long-term effect needs long-term follow-up observation.
Objective To observe the clinical effects of penetrating keratoplasty and lamellar keratoplasty.Methods 230 cases(230eyes) were followed up,including 190 eyes undergoing penetrating from the Department of Ophthalmology, the First Affiliated Hospital of kunming medical college,Kunming 650032 yunnan Province,keratoplasty(PKP) and 40 eyes undergoing lamellar keratoplsty(LKP).The period of follow-up ranged from 3 to 38 months,15.4 months in average.The post-operative vision,rejection,recurrence and secondary glaucoma were observed and compared.Results The post-operative vision of the patients managed with PKP significantly increased(P<0.01).22 eyes of rejection(12. 1%),7 eyes of recurrence(3.7%) and 21 eyes(11%) of secondary glaucoma were found in the PKP group.Compared with that before surgery,the vision increase of the patients managed with LKP were not significant(P>0.05).2 eyes of rejection(5%),1 eye of recurrence(2.5%) and no secondary glaucoma were found in the LKP group.Conclusion Compared with lamellar keratoplasty,penetrating keratoplasty leads to good visual results while the risk of rejection and secondary glaucoma were significantly increased.
