A-P method may calculate IOL power

Article

The anterior-posterior (A-P) method is effective for calculating IOL power when preoperative LASIK data is unavailable.

The anterior-posterior (A-P) method is effective for calculating IOL power when preoperative LASIK data is unavailable, states a paper in the Journal of Cataract and Refractive Surgery.

A retrospective case series led by Dr Megumi Saiki, Department of Ophthalmology, Keio University Hospital, Tokyo, Japan, included eyes undergoing phacoemulsification and IOL implantation after myopic LASIK.

The A-P method includes modifying the double-K method using the SRK/T formula. The accuracy of the A-P method was compared with other formulae that do not require preoperative data and formulae that do require preoperative data.

The median values of the arithmetic and absolute prediction errors with the A-P method were 0.16 D and 0.54 D, respectively. Prediction errors using the A-P method were within ±0.50 D in 46.4% of eyes and within ±1.00 D in 75.0%. Using the A-P method is a successful option for calculating IOL in eyes undergoing cataract surgery.
