Double-step calculation of the intraocular lens power in lens opacities excluding the measurement of axial eye length by optical biometry. A clinical case

Российский офтальмологический журнал, 2023
The main source of intraocular lens (IOL) power calculation errors in phacoemulsification (PE) is axial length (AL) measurement inaccuracy in cases if optical biometry cannot be used.bto describe an original double-step method of IOL power calculation in

Intraocular light scatter as modeled through a stratified medium [PDF]

, 2001
Intraocular light scatter is modeled through a stratified medium. It is shown that the eye lens possesses properties of an interference filter. In conditions that may mimic opacification, as found with cataract formation, such a filter may have stop ...

Intraocular lens power calculation for the equine eye

BMC Veterinary Research, 2018
Background Phacoemulsification and intraocular lens (IOL) implantation during cataract surgery in horses occur with increasing frequency. To reduce the postoperative refractive error it is necessary to determine the proper IOL power. In the present study

Evaluation of repeatability and agreement of two optical biometers for intraocular lens power calculation. [PDF]

Sci Rep
The repeatability of two biometers (Lenstar-LS900 and Eyestar-900) to measure ocular parameters and intraocular lens (IOL) power calculation, and their agreement were evaluated. 134 eyes of 134 participants were measured thrice with each biometer.

Relationship between pterygium and biometric error in intraocular lens calculation for cataract surgery [PDF]

Revista Brasileira de Oftalmologia
Objective: To evaluate the effect of pterygium on different biometric intraocular lens calculation formulas. Methods: This is an interventionist, prospective, and non-randomized study. We included patients who underwent pterygium surgery and performed a
