Purpose: To compare the accuracy of central true net corneal power (cTNP) and mean true net corneal power (mTNP) of the Pentacam system to give a keratometry (K) reading for calculating IOL (intraocular lens) power in eyes following refractive surgery. Methods: Refraction, an automated K-reading (Km), cTNP and mTNP were measured for 15 eyes that required cataract surgery and had previously undergone refractive surgery. The difference between postoperative manifest refraction values and target refraction values calculated with the SRK/T formula using cTNP were compared with the one using mTNP. Results: The mean deviation from the desired post-cataract refractive outcome was 0.60 diopter (D) ±0.47 (standard deviation) using cTNP; 0.75±0.54 using mTNP (p=0.386). The actual refraction was within ±0.50D of the intended refraction for 60% (cTNP) and 33.3% (mTNP) of eyes, and within ±1.00D for 93% (cTNP) and 66.7% (mTNP) of eyes. Conclusions: Although not statistically significant, the cTNP showed better accuracy than mTNP to give a keratometry (K) reading for post-refractive surgery eyes requiring cataract surgery.
