Purpose

The residual refractive error is one of the main causes of dissatisfaction after cataract surgery.The objective of this study was to investigate the accuracy of the common biometry formulas (SRK/T, Hoffer Q, Holladay 1, Haigis, or Kane) in non-complicated caratact surgery implanting a monofocal lens

Setting/Venue

Predictability of the comon biometry formulas according to axial lenght in cataract surgery 

Methods

A cross-sectional observational design was based on data collected in the medical records of 141 patients who underwent cataract surgery. One eye of each patient was selected. Patients were classified according to axial length (AL) into three groups: AL ≤ 22 mm: short eyes; 22 < AL < 25 mm: medium eyes; AL ≥ 25 mm: long eyes. The implanted lens was Asqelio ® monofocal (AST), a spherical and biconvex hydrophobic acrylic lens. The constant was optimized.Predictability was  The biometry formulas predictability was compared calculating the percentage of eyes within ±0.5 D, ±0.75 D, and ±1.00 D 

Results

In the AL<22mm group ( classified as short eye), the formula with the highest percentage of eyes within the ±0.5 range was the SRK/T, followed by the Kane formula. In the 22

Conclusions

SRK/T and Kane have proven to be reliable and effective formulas in the refractive calculation of this particular lens for short and long eyes. Kane also performed well on medium eyes, making it the formula that has worked best overall.
