Abstract Details

Purpose:

To compare the accuracy of refractive outcome of the implantation of intraocular lenses (IOLs) with different diopter (D) intervals after cataract surgery.

Setting:

Korea University College of Medicine, Seoul, South Korea

Methods:

Forty patients underwent uncomplicated phacoemulsification with implantation of a 0.50 D interval Akreos AO (Bausch & Lomb, Rochester, NY; 40 eyes) IOL in one eye and a 0.25 D interval Softec HD™ (Lenstec Inc., St. Petersburg, FL; 40 eyes) IOL in the other eye. The refractive prediction error of the IOL with a standard deviation (SD) of ±0.40 D was compared with that of the IOL with a SD of ±0.11 D through Monte Carlo simulations. The percentages of eyes that achieved a postoperative refractive prediction error within ±0.50 D or ±0.25 D at one month after surgery were compared.

Results:

In clinical study, the percentage of eyes that achieved a postoperative refractive prediction error within ±0.50 D by the Haigis formula in the Softec HD™ group (85.0%) was significantly greater than that in the Akreos AO group (57.5%; P = 0.027). In Monte Carlo simulations, all percentages of eyes that achieved a postoperative refractive prediction error within ±0.25 D by the Haigis and SRK/T formulas in the Softec HD™ group were significantly greater than those in the Akreos AO group.

Conclusions:

The IOL with a 0.25 D interval was more accurate than the IOL with a 0.50 D interval in predicting refractive outcome after cataract surgery.
