Clinical Observation Of Phacoemulsification Cataract Surgery Combined With Simple Excision Of Pterygium

Objective:This study was aimed to assess the Safety and effectiveness,the change of the refractive state,the Accuracy of IOL prediction accuracy after simultaneous pterygium excision and phacoemulsification with IOL implantation.Methods:We retro-spectively reviewed the clinical charts of 44 cases (48eyes)who was given simultaneous pterygium excision and phacoemulsification with IOL in the First Affiliated Hospital of Guangxi Medical University, from January 2014 to July 2015. All the eyes were examined before operation and 6 months after operation.Results:(1) The visual acuity improved after surgery,uncorrected visual acuity(UCVA) was 0.35±0.23, best corrected visual acuity(BCVA) was 0.60±0.22; (2) The postoperative corneal astigmatism (1.48±0.86) D reduced compared with preoperative (3.87±3.74) D (P<0.01); (3)The mean preoperative corneal curvature (43.46±1.81) D significantly increased to (44.21 ± 1.72) D (P<0.01); (4) The preoperative prediction error was (0.24 ± 0.02) D,the actual postoperative refractive error was (1.67 ± 0.34) D,the difference was statistically significant(P<0.05). (5) The postoperative refractive error value was (1.01 ± 0.11)D,it was significantly correlate with the corneal curvature difference between preoperative and postoperative(P<0.01); (6)The postoperative visual function and quality indicators of the amount of survival table score were: 83.75 ± 13.76,85.27 ± 13.46, significantly increased (P<0.01) compared with preoperative. (7)Four eyes(8.33%) developed a slight recurrence of pterygium, there eyes(6.25%) developed posterior capsular opacification. Conclusion:Simultaneous pterygium excision and phacoemulsification with IOL can improve visual acuity, the corneal astigmatism reduced,the visual function and quality indicators of the amount of Life Scale scores improved, but the accuracy of IOL prediction is still poor.
