Mitsukawa T, Suzuki Y, Momota Y, et al. - In this investigation involving 20 healthy volunteers (7 males and 13 females, aged 22– 34 years) with no history of eye disease except for refractive errors, researchers analyzed changes in the crystalline lens during accommodation and the impact of cycloplegics by swept-source anterior-segment optical coherence tomography (AS-OCT). Biometric parameters, including anterior chamber depth, lens thickness, and anterior and posterior curvature of the lens (ACL and PCL), have been measured utilizing AS-OCT (CASIA2). According to findings, the AS-OCT system was capable of simultaneous visualization of all optical components of the anterior segment in a single frame. No significant differences were found in all lens parameters despite having 5.0 D accommodative stimulation in both eyes with cycloplegia. The findings show that both tropicamide/phenylephrine and cyclopentolate eyedrops have ample cycloplegic effects in young adults.
