To compare the development of glistenings after implantation of a hydrophobic acrylic intraocular lens (IOL) (AcrySof SA60AT) and a hydrophilic IOL (BL27) and evaluate the effect on corrected distance visual acuity (CDVA) and contrast sensitivity 9 years postoperatively.
St. Erik Eye Hospital, Stockholm, Sweden.
Prospective randomized clinical trial.
One of 3 experienced cataract surgeons performed standard phacoemulsification in 1 eye of each patient. The patients were randomized to implantation of a hydrophobic acrylic IOL or a hydrophilic acrylic IOL. Both IOLs had sharp posterior edges. The CDVA and contrast sensitivity were measured 9 years postoperatively. Scheimpflug images of the IOLs were obtained to analyze glistenings, which were graded subjectively at the slitlamp and quantified objectively with digital image analysis using computer software.
Seventy-eight of the 120 patients were available for the 9-year follow-up examination. Patients with the hydrophilic IOL had statistically significantly fewer glistenings (P < .001). The development of glistenings was not correlated with IOL power, CDVA, or contrast sensitivity.
After 9 years, the hydrophobic IOL developed more glistenings than the hydrophilic IOL. Glistenings did not affect CDVA or contrast sensitivity.
