Comparison of IOL--master and ultrasound biometry in preoperative intra ocular lens (IOL) power calculation.
Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included...
متن کاملAccuracy of intraocular lens power calculations using the Zeiss IOL master. A prospective study.
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. ...

Treatment.-Gutt. pilocarpine 1 per cent. four times a day failed to 'control the intraocular pressure, which varied between 45 and 79 mm. Hg Schiotz. On December 10, 1956, a filtration operation was performed, consisting of combined anterior flap sclerotomy, cyclodialysis, and basal iris inclusion (Stallard, 1953). There were apparently no operative complications. On the sixth post-operative da...
متن کاملShape optimization of an accommodative intra-ocular lens
Cataract surgery consists in replacing the clouded or opacified crystalline lens by an Intra-Ocular Lens (IOL) having the same mean dioptrical power. Clear vision is then achieved at a given distance and glasses are needed in many situations. A new kind of IOL, potentially accommodative, is proposed. Its design is based on the deep understanding of the accommodation mechanism and on the mathema...
متن کاملThe effect of ocular biometric factors on the accuracy of various IOL power calculation formulas
BACKGROUND To evaluate how differences in ocular biometry affects the Hoffer Q, Holladay 1, SRK/T, and Haigis intraocular lens power calculation formulae predictions. METHODS This study was performed on 91 eyes of 91 patients who underwent uneventful cataract surgery. Ocular biometry values were measured using the IOL Master 500, and intraocular lens (IOL) power was calculated using the Haigi...
