SPECTRAL TRANSMITTANCE CURVES (PERCENTAGE OF ULTRAVIOLET TRANSMITTANCE) Figure 2 100 90 TRANSMITTANCE (%) NOTES: • The cutoff wavelength and the spectral transmittance curves presented here represent the range of transmittance values of IOLs made from ultraviolet-absorbing PMMA. • Measurements were direct transmittance using a disc of thickness equivalent to the optic center. • UV cutoff at 10% T is 374 nm (-10.0 diopter lens). UV cutoff at 10% T is 388 nm (+34.0 diopter lens). • Human lens data from Boettner and Wolter (1962). MODE OF ACTION These posterior chamber intraocular lenses are...

The physician must determine the benets to be derived from lens implantation when such conditions exist. Patients who experience surgical complications associated with the cataract extraction procedure...

Cumulative Incidence % Cumulative Incidence % Hyphema Macular Edema Pupillary Block Secondary Glaucoma Cyclitic Membrane Vitritis Endophthalmitis Retinal Detachment Corneal Edema Iritis Lens Dislocation Fifty-one (10.1%) cohort patients receiving the non-UV-absorbing lenses (CR-1, GR-1, SM-1) experienced one or more of the above complications. However, these complications occurred early in the postoperative time frame and appear to be associated with the cataract extraction. Ten patients (2.0%) were reported to have these complications 12-14 months after surgery. Ninetyone (17.9%) cohort...
