The AcrySof ReSTOR IOL and AcrySof Natural ReSTOR IOL provided good visual performance at distance and near under photopic and mesopic conditions. Intermediate vision with both models was reduced compared with distance and near vision.

A larger pupil was correlated significantly with better distance visual acuity and with worse near visual acuity. For all pupil diameters, intermediate visual acuity worsened significantly as the distance of the test increased. Distance contrast sensitivity was better with larger pupils at all spatial frequencies in bright-light and dim-light conditions.

Bilateral implantation of the distance-dominant bifocal 447D IOL provided good simultaneous distance, near, and intermediate vision with improved contrast sensitivity under photopic and mesopic conditions.

The Acri. Twin bifocal diffractive IOL implanted in the ciliary sulcus using the piggyback technique provided pseudoaccommodation in emmetropic pseudophakic eyes. Binocular implantation of these IOLs should be performed considering the differences in light distribution of the distance-weighted IOL and the near-weighted IOL models.

We present 4 patients who had laser in situ keratomileusis and were referred to our clinic with a diagnosis of infectious keratitis. Laser in situ keratomileusis was performed in all cases in the same operating room by different surgeons between April and May 2002. A partial penetrating keratoplasty was performed in all patients to control the process. A study of the corneas demonstrated the presence of the fungus Acremonium in all cases. Rigid asepsis during the surgical procedure is important to prevent this serious complication.
