## How to easily perform the Haigis triple optimization

The Haigis FormulaThe Haigis formula is the simplest thin lens formula possible. The ELP (= d value) is predicted using a multiple regression taking ACD and AL as inputs. def Haigis(AL, R, ACD,

Third generation formulas are based on thin lens optics. They have the same "skeleton". The value they use to determine the corneal power from the anterior radius of curvature differ - neither do

Descemet membrane endothelial keratoplasty (DMEK) was introduced in 2006 by Melles et al (1). This procedure revolutionized the management of endothelial pathologies by allowing a near perfect anatomical replacement of the diseased endothelium.

The SRK/T formulaThe SRK/T formula (1,2) has long been one of the most popular IOL calculation methods : it is still widely used and its optimized constant is often used to

In this post, we will review the PEARL online calculator features, discuss the mechanisms behind them, and their applications. Regular EyesThis page allows the user to perform a calculation for 'standard eyes', i.
