Management of the subluxated crystalline lens: A review
Clinical and Experimental Ophthalmology, 2021Cataract surgery for the subluxated crystalline lens is challenging. A thorough preoperative evaluation is important to determine the appropriate surgical approach for lens removal and the subsequent technique of intraocular lens placement.

Age-related changes in crystalline lens tilt and decentration: swept-source OCT study
Journal of cataract and refractive surgery, 2021In this study, the crystalline lens tilt and decentration were measured using swept-source coherence tomography. The crystalline lens position correlated with ocular parameters and may change over time.

The spectral dispersions of rabbit, rat, pigeon, and human crystalline lens material have been measured with a Pulfrich refractometer. The refractive indices all increase rapidly at the violet end of the spectrum so tat the chromatic aberrations of the eyes of these species cannot be derived adequately from Cornu's formula, as had previously been ...

The human crystalline lens is the second most important refracting element of the eye. The lens functions primarily in accommodative vision. The lens doubles in volume between birth and age 70. Approximately at age 40, the lens loses its ability to accommodate because of loss of pliability, and at age 70 the transparency of the lens is reduced ...

Abscess of the Crystalline Lens
American Journal of Ophthalmology, 1943Perforating injuries of the globe frequently involve the lens by causing perforation of the anterior capsule and the production of varying stages of traumatic cataract. If infection accompanies the perforation, a purulent infiltration results in abscess of the lens.

A Model for Crystalline Lens Accommodation
Comprehensive Therapy, 2003When a slight equatorial pull is applied to the crystalline lens, the center thickens, the central surfaces steepen, and the optical power increases. These findings are consistent with Schachar's theory of accommodation.
