Abstract Details

Purpose:

To investigate the effects of topical cyclopentolate on ocular biometry parameters and intraocular lens (IOL) power calculation in healthy adults.

Setting:

Turgut Ozal University Hospital, Department of Ophthalmology, Ankara, Turkey.

Methods:

This study prospectively enrolled 30 eyes of 30 participants with a mean age of 22.1 ± 4.7 years (range, 18 to 37 years). Axial length (AL), anterior chamber depth (ACD), corneal curvature, and white-to-white (WTW) measurements were performed with and without cycloplegia by 45-minutes interval. A partial optical coherence interferometry (AL-Scan, Nidek CO, Aichi, Japan) was used for ocular parameter measurement .The IOL powers were calculated using four formulas: SRK-T, Holladay 1, Hoffer Q, and Haigis. The pre- and postcycloplegic measurements were evaluated by using the paired t-test.

Results:

Cycloplegia had no significant effect on AL, keratometric values and WTW except ACD, which significantly increased postcycloplegia (0.10 ± 0.06 mm) (p less than 0.001). However, no significant change for IOL power was detected using the all four formulas.

Conclusions:

Topical application of 1% cyclopentolate can increase ACD with no significant effect on IOL power calculation by Nidek AL-Scan optical biometry.
