Comparison of ocular biometry and intraocular lens power using a new biometer and a standard biometer.
PURPOSE To compare the repeatability and reproducibility of ocular biometry and intraocular lens (IOL) power obtained with a new optical biometer (AL-Scan) and a standard optical biometer (IOLMaster 500). SETTING Siriraj Hospital, Mahidol University, Bangkok, Thailand. DESIGN Prospective comparative study. METHODS Two independent operators measured eyes with cataract using both biometers....
متن کاملIOLMaster keratometry for the calculation of toric intraocular lens power and orientation
In the implantation of intraocular lenses (IOL) stringent requirements are made on achieving the refractive target. This necessitates the exact determination of the basic data needed for IOL power calculation – both the axial length and, in particular, the corneal power – and additionally the cylinder power and its axis in the case of a toric lens. This gives rise to the question, especially fo...
متن کامل[Contact lenses and intraocular lens power calculation: refractive surprise using the IOLMaster non-contact biometric method].
Dear Sir, This letter is to alert about the danger of carrying out biometric calculations for the intraocular lens without being aware that the patient may be using a contact lens. This warning is valid even when the highest precision research technology is being utilised. At present, errors in the calculation of the intraocular lens (IOL) are the most frequent cause of lens exchanges as well a...
متن کاملIntraocular Lens Power Calculation Using IOLMaster and Various Formulas in Short Eyes
PURPOSE To evaluate the predictability of intraocular lens (IOL) power calculations using the IOLMaster and four different IOL power calculation formulas (Haigis, Hoffer Q, SRK II, and SRK/T) for cataract surgery in eyes with a short axial length (AL). METHODS The present study was a retrospective comparative analysis which included 25 eyes with an AL shorter than 22.0 mm that underwent uneve...
متن کاملRefractive outcomes of intraoperative wavefront aberrometry versus optical biometry alone for intraocular lens power calculation
PURPOSE To compare the outcomes of intraoperative wavefront aberrometry versus optical biometry alone for intraocular lens (IOL) power calculation in eyes undergoing cataract surgery with monofocal IOL implantation. METHODS Preoperative data were obtained with the IOLMaster. Intraoperative aphakic measurements and IOL power calculations were obtained in some patients with the optiwave refract...
