IOLMaster 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 کاملAccuracy of intraocular lens power calculation in paediatric cataract surgery.
AIMS To determine the accuracy of intraocular lens (IOL) power calculation in a group of pseudophakic children. METHODS A retrospective analysis of biometric and refractive data was performed on 52 eyes of 40 infants and children, who successfully underwent cataract extraction and IOL implantation. The following parameters were included: age at the time of surgery, keratometry, axial length, ...
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. ...
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...
