Abstract Details


Purpose: to assess the exact IOL location and relation to the enlarged capsular bag in high myopic eyes by Ultrasonic biomicroscopy (UBM). Because an IOL manufactured with only one diameter did not anatomically fit all capsular bags.


Ophthalmology Department, Banha University Hospitals, Egypt.



this prospective randomized masked clinical trial concluded 80 high myopic eyes (with axial length greater than 26.5 mm), that were planned for refractive lens exchange or cataract extraction). They were equally divided into 2 equal groups that underwent phacoemulsification with implantation of acrylic one-piece IOLs (group A), and 3-piece IOLs (group B). UBM was used to measure the diameter of the capsular bags and implanted IOLs and assess their position.


Results: The mean diameter of the Implanted IOLs was 10.01 ᄆ 0.31 mm in group A, and 10.40 ᄆ 0.42 mm in group B which was statistically significant larger. (P<0.05) Statistically significant correlations between the diameters of the capsular bags and the diameters of the implanted IOLs were found to be ヨve in group A (r = ヨ.56), and +ve in group B (r=0.86) The mean diameter of the capsular bags was 11.97 ᄆ 0.65 mm in group A, and 11.4 ᄆ 0.72 mm in group B with no statistically significant difference. (p>0.05)


This study showed lack of fitting of both IOL types in relation to the enlarged capsular bags. However, 3- piece IOLs showed better anatomical fitting in high myopes. Our results point to the importance of the adaptability of the IOL diameter to the different bag sizes and that the correlations of the IOL diameter with the power and the axial length of the eye should result in better capsular bag fitting.
