Abstract
Purpose: :
Recently, many different types of hydrophobic acrylic intraocular lenses (IOLs) were produced. In this study, we compared the characteristics of these IOLs and evaluated the clinical results after cataract surgery.
Methods: :
In this study, 120 eyes were performed phacoemulsification and three peace acrylic IOLs (MA60BM, Alcon; VA60BB, HOYA), single peace acrylic IOL (SA60AT, Alcon) or blue–block acrylic IOL (YA60BB, HOYA) were randomly selected and implanted. The clinical data were evaluated for 3months postoperatively. The clinical results were statistically analyzed by Fisher's PLSD.
Results: :
There were no significant differences between the four types of acrylic IOLs regarding visual acuity, intraocular pressure, corneal endothelial cell loss and aqueous flare postoperatively. The refractive errors of SA60AT, VA6OBB, YA60BB and MA60BM are 0.43D, 0.38D, 0.37D and 0.69D respectively at 3 months postoperatively. The IOL tilting of SA60AT, VA60BB, YA60BB and MA60BM are 0.27°, 0.25°, 0.23° and 0.34° respectively at 3 months postoperatively. The IOL decentration of SA60AT, VA60BB, YA60BB and MA60BM are 4.4mm, 4.1mm, 4.0mm and 5.4mm respectively at 3 months postoperatively. The mechanical properties of the SA60AT, VA60BB and YA60BB are better than the MA60BM.
Conclusions: :
Newly developed IOLs have different characteristics. Good clinical results were obtained using hydrophobic acrylic IOLs, however, the amounts of refractive errors are only different at 3 months postoperatively. The IOL tilting and decentration in the SA60AT, VA60BB and the YA60BB group was lower than the MA60BM after surgery. The findings suggest that the fixation of the SA60AT, VA60BB and the YA60BB in lens capsule is fabulous. These IOLs resulted in minimum refractive errors during the early postoperative period. The retrospective analysis of clinical data is important to evaluate the different IOLs.
