Refractive surgery
Planning and simulation of laser refractive surgery.
A simulator that predicts residual stromal thickness and ablation parameters for both eyes to make refractive planning safer.
Direct accessDesign a custom multifocal corneal profile to correct presbyopia by LASIK or PRK.
Direct accessCataract & IOLs
Calculation tools for cataract surgery and intraocular lens selection.
AIOLsci predicts the performance of an intraocular lens (IOL) from the optical characteristics specific to each cornea.
Direct accessDetermines the power of the replacement IOL in the event of a refractive surprise in a pseudophakic eye, without relying on conventional calculation formulas.
Direct accessA next-generation formula that combines thick-lens optics and machine learning to compute intraocular lens power.
Direct accessA tool that measures the performance of any IOL power formula on your own patients and automatically optimises the constants.
Direct accessAstigmatism
Vectorial analysis and correction of corneal and lenticular astigmatism.
An interactive tool that computes the optimal orientation of a toric phakic IOL (ICL, IPCL…) to minimise residual postoperative astigmatism.
Direct accessAn interactive tool that computes and visualises the optimal orientation of a toric IOL to minimise residual astigmatism after cataract surgery.
Direct accessA vectorial-analysis tool to add astigmatism components and visualise the resulting cylinder.
Direct accessAberrometry & wavefront
Wavefront analysis, optical aberrations and quality of vision.
Visualise the expected retinal image quality from measured optical aberrations.
Direct accessVisualise the impact of a change in pupil diameter or centring on the wavefront, the refraction and the retinal image quality.
Direct accessTurn Zernike coefficients into refractive power maps that can be read directly in the clinic.
Direct accessExplore in real time how variations in corneal asphericity (Q) modulate spherical aberration, multifocality and visual performance.
Direct accessAn experimental instrument that turns optical aberrations into sound, so the wavefront can be perceived by ear.
