WebJul 10, 2024 · Calculating the best intraocular lens power for patients undergoing cataract surgery remains a key part of achieving patient satisfaction. But despite constant advances in biometry and ever-improving power-calculation formulas, most practices are still only getting about 80 percent of patients within 0.5 D of the target refraction. WebPatient measurements were carried out on both devices on the same day by the same optometrist within the standard preoperative calculation of the intraocular lens before cataract surgery. Evaluated and statistically analyzed biometric data were axial lenght, anterior chamber depth, average keratometry and lens thickness. Results:
WebPurpose: To assess the performance of multiple intraocular lens (IOL) formulas in eyes with keratoconus. Methods: Eyes with stable keratoconus scheduled for cataract surgery with biometry measurements on the Lenstar LS900 (Haag-Streit) were included. Prediction errors were calculated using 11 different formulas, including two with keratoconus modifiers.

WebDavid F. Chang MD, in Immediately Sequential Bilateral Cataract Surgery (ISBCS), 2024 Despite having far better biometry and IOL formulae than 2 decades ago, there remains a benefit for many patients to assess the refractive outcome of their first eye, before deciding on the second eye strategy [6].Some achieving emmetropia with a monofocal or EDOF … WebWhy is Biometry done? When cataract (clouding of the lens of your eye) occurs, your eyes lose the focusing power that the lens provides. In order to overcome this, your eyes are …
WebData quality for optical biometry is frequently diminished in cases of very dense cataracts and posterior subcapsular cataracts, and this can be quantified in the form of signal-to-noise ratio (SNR). 7–9 Olsen et al reported a minimum difference in axial length (AL) between optical biometry and US at an SNR value of ≥2.1.
