PURPOSE Partial Coherence Interferometry (PCI) is a fast, noncontact method to calculate lens implant power for cataract surgery. It has been reported as a potentially more accurate method than ultrasound biometry. Prospective study of the refractive outcomes of a consecutive series of patients undergoing phacoemulsification surgery with preoperative biometry by both ultrasound A-scan and PCI. ...

OBJECTIVE To ascertain whether a new instrument that uses partial coherence interferometry technology (Intraocular Lens Master [IOLm]) or ultrasound biometry provides a more accurate prediction of refractive outcomes in cataract surgery. METHODS This was a retrospective medical record review of 421 eyes of 304 patients who underwent cataract surgery with the IOLm and ultrasound biometry from ...

OBJECTIVES To compare ocular biometry of the contralateral eyes of individuals seen with acute angle closure (AAC) with eyes of population-based control subjects, and to assess novel provocative tests to study the mechanism of AAC. DESIGN Prospective case-control study. PARTICIPANTS Chinese persons seen as incident cases of AAC and Chinese population-based controls. METHODS Slitlamp asses...

Purpose : to study the correlation between acoustic and morphometric parameters of optic nerve (ON) anthropometric data in healthy young people. Material methods . The research involved 24 volunteers (48 eyes), including 9 men 15 women, average age was 25.0 ± 1.9 years. Anthropometry included measurements height, weight, body mass index (BMI). Ultrasound examination retrobulbar part ON measurem...

PURPOSE To investigate the distribution of axial length, anterior chamber depth, lens thickness, vitreous chamber depth, and central corneal thickness in children at different age groups. METHODS We studied 364 eyes in 182 children with ages between 1 and 12 years. Axial length, anterior chamber depth, lens thickness, and vitreous chamber depth were measured by ultrasound biometry. Central co...
