Randomized Controlled Trial Comparative Study
Comparison of multifocal and monovision soft contact lens corrections in patients with low-astigmatic presbyopia.
The purpose of this study was to assess visual performance and patient satisfaction with two presbyopic soft contact lens modalities. ⋯ The majority of our patients preferred multifocals to monovision, most likely because the Bausch & Lomb SofLens Multifocal provides excellent visual acuity without compromising stereoacuity to the same degree as monovision.

Randomized Controlled Trial
Overnight corneal reshaping versus soft disposable contact lenses: vision-related quality-of-life differences from a randomized clinical trial.
The purpose of this article is to evaluate patients' visual acuity, symptoms, and perceptions of vision-related quality of life in a randomized crossover clinical trial of overnight corneal reshaping (OCR) and daily wear soft lenses (SCL). ⋯ In subjects with mild myopia who experienced both SCL and OCR, better visual acuity and less glare resulted from SCL wear, whereas activity limitations, symptoms, and dependence on refractive correction were less troublesome with OCR wear. When the study was completed, 67.7% chose OCR lenses worn only while sleeping, whereas 32.3% preferred 2-week disposable soft lenses worn during the day as their preferred correction.

Waldenström's macroglobulinemia is a rare, malignant lymphoplasmacytic disorder characterized by the monoclonal proliferation of immunoglobulin type M (IgM) producing B-lymphocytes. Ocular manifestations of Waldenström's macroglobulinemia have been described in association with the conjunctiva, cornea, uvea, retina, and periocular adnexa. Only rarely have macular findings, particularly serous macular detachments, been described in the presence of monoclonal hypergammaglobulinemias. The majority of reports to date have documented resolution of these serous macular detachments after treatment with blood plasmapheresis. This report presents a case of bilateral, persistent serous macular detachments in the presence of Waldenström's macroglobulinemia. ⋯ Although the funduscopic manifestations of excess serum immunoglobulins are typically the sequelae of circulatory stasis, the serum hyperviscosity induced in Waldenström's macroglobulinemia has been shown on rare occasions to induce serous macular detachments. Physical elimination of the excess macroglobulins through plasmapheresis is quite effective in resolving the neurosensory detachments induced by Waldenström's macroglobulinemia. Only a fraction of neurosensory detachments resulting from Waldenström's macroglobulinemia persist despite multiple plasmapheresis treatments. Novel angiographic evidence of retinal pigment epithelium atrophy beneath the area corresponding to the serous detachment provides a plausible explanation for unresponsive nature of this presentation. Identification of this rare variant of the classic angiographically silent macula known to occur with Waldenström's macroglobulinemia can aid the clinician in determining a patient's potential response to plasmapheresis and their final visual prognosis.

: The purpose of the study was to monitor the efficacy of corneal refractive therapy (CRT) lenses to reduce myopia over a 4-week period. Refractive error, keratometry, high and low contrast acuity, and subjective vision after 28 days of using CRT contact lenses were measured. ⋯ : CRT lenses significantly reduced myopia, improved visual acuity and subjective vision, and flattened central corneal curvature. Maximal effect was achieved after 10 days and was maintained for the rest of the study period.
