To compare glistenings 9 years after cataract surgery with implantation of a hydrophobic or a hydrophilic acrylic intraocular lenses (IOLs) and evaluate the effects on the corrected distance visual acuity (CDVA) and contrast sensitivity
St. Erik Eye Hospital, Stockholm, Sweden
Cataract surgery with standard phacoemulsification was performed in one eye of 120 patients in this prospective study. The patients were randomized to either a hydrophobic lens, AcrySof SA60AT, or a hydrophilic lens, BL27, both with a sharp edge design. Nine years postoperatively, CDVA and contrast sensitivity were measured with Optec® 6500 Vision Tester. Scheimpflug images were obtained to evaluate glistenings, which were graded subjectively at the slit lamp and quantified objectively by digital image analysis using computer software.
The BL27 IOLs had significantly fewer glistenings (P=0.045). We found a good correlation between the subjective grading of glistenings and objective computer processed image grading R=0,54, (P<0,001). The glistenings were not correlated with the IOL power (P=0.55), CDVA (P=0.13), or contrast sensitivity (P=0.065).
The hydrophobic AcrySof SA60AT IOL developed more glistenings compared to the hydrophilic BL27 IOL. Glistenings did not affect CDVA or contrast sensitivity.
