Diurnal axial length fluctuations in human eyes.
PURPOSE This study sought diurnal variations of eye length in human subjects, analogous to those reported in laboratory animals. METHODS Seventeen subjects, ages 7 to 53 (median 16) years and mean spherical equivalent refractive error -0.68 D (range, -3.00 to +1.00 D), underwent axial length measurements at multiple times during the day between 7 AM and 1 AM the following day, using partial c...
متن کاملAccuracy of axial length measurements from immersion B-scan ultrasonography in highly myopic eyes.
AIM To evaluate the accuracy of axial length (AL) measurements obtained from immersion B-scan ultrasonography (immersion B-scan) for intraocular lens (IOL) power calculation in patients with high myopia and cataracts. METHODS Immersion B-scan, contact A-scan ultrasonography (contact A-scan), and the IOLMaster were used to preoperatively measure the AL in 102 eyes from 102 patients who underwe...
متن کاملAxial eye length measurements pre-and post-laser-assisted in situ keratomileusis using the IOL Master: a pilot study
PURPOSE A preliminary study in order to test the accuracy of the IOL Master in detecting axial eye length changes after laser-assisted in situ keratomileusis and to correlate the findings with the theoretical ablation depth. METHODS Pre-and postoperative axial eye length measurements were performed in 10 consecutive eyes that underwent laser-assisted in situ keratomileusis with the Alcon Lada...
متن کاملAxial length measurement techniques in pediatric eyes with cataract.
Globe axial length (AL) in children is commonly measured using either contact or immersion technique. Office measurement of AL can be difficult in young children and infants and must often be done under anesthesia in an eye that is unable to cooperate with precise fixation and centration. Contact A-scan measurements yield shorter AL, on average, than immersion A-scan measurements in pediatric e...
متن کاملChange in Axial Length Pre and Post Cataract Surgery Measured with IOL Master
Objective: Cataract surgery with intraocular lens (IOL) implantation tries to get a refractive result nearby to the optic emmetropia. So an accurate IOL power calculation is mandatory, and axial length (AL) measurement is one of the most influential parameter in this calculation. IOL Master is one of the most popular devices to measure AL, which uses the same group refractive index of the lens ...
