Abstract Details


To investigate the effects of cyclopentolate hydrochloride 1% on the main numerical parameters of anterior segment with Pentacam rotating Scheimpflug camera in cataract patients.


Akdeniz University Hospital Ophthalmology Department Antalya, Turkey


Pentacam measurements of 68 eyes of 45 cataract patients before (group 1) and after 45 min of cyclopentolate hydrochloride 1% (group 2) instillation were performed and compared with each other. For comparison of the test parameters, paired t-test in the groups and unpaired t-test in between the groups were used.


Mean ages in the study were 67,12 (range 37 and 87 years). Measurements between group 1 and group 2 were significantly different for the parameters of anterior chamber depth (ACD) and anterior chamber volume (ACV). Central corneal thickness (CCT), K1, K2, Kmax and corneal astigmatism were similar in all groups.


ACD and ACV are the important refractive parameters that increase significantly after cycloplegia. Effects of cycloplegia on these parameters for Pentacam measurements should be regarded for proper clinical interpretation in cataract patients, such as refractive procedures and intraocular lens power measurements.
