Visual acuity tolerance to residual refractive errors in patients with an apodized diffractive intraocular lens.
To assess visual acuity tolerance to defocus caused by residual refractive errors after clear lens extraction (CLE) with apodized diffractive intraocular lens (IOL) implantation. ⋯ Correction of distance residual refractive error improved distance visual acuity in patients with apodized diffractive IOLs. However, near visual acuity was maintained whether the residual refractive error was corrected or not.

Randomized Controlled Trial Comparative StudySeparate and additive mydriatic effects of lidocaine hydrochloride, phenylephrine, and cyclopentolate after intracameral injection.
To assess the separate mydriatic effect of lidocaine hydrochloride (Xylocaine), cyclopentolate, and phenylephrine after intracameral injection and evaluate whether intracameral Xylocaine and phenylephrine without cyclopentolate provide sufficient pupil dilation for cataract surgery. ⋯ Xylocaine plus phenylephrine injected intracamerally gave adequate intraoperative pupil dilation in routine phacoemulsification surgery. Cyclopentolate administrated intracamerally had no immediate additive mydriatic effect to intracameral Xylocaine combined with phenylephrine.
