Purpose :Evaluation the accuracy of intraocular lens (IOL) calculations and axial length (AL) performed using contact and immersion A-scan biometry. Materials and Methods :In this observational prospective study, 60 cataractous eyes of 60 patients attending the Ophthalmic Clinic at Almouassat University Hospital from 1 Mars 2016 until 1 December 2016 were enrolled. They were divided randomly into tow group. Group I patients had A-scan biometry using Contact Technique, while Group II patients had A-scan biometry using Immersion Technique .Keratometery was made, then Axial Length calculations and Intraocular Lens (IOL) Power calculations were made using SRKT formula. The patients were followed after the surgery in one day, one week, one month .Main Outcome Measures were Prediction Error (PE), Absolute Prediction Error (Absolute PE), and Predictable Refraction in the Spherical Equivalent (SE) form. Results: The mean age of the patients was 65.37 years(range 46-91 years. The mean PE in Immersion -0.24 D (SD ±0.67D) and in Contact +0.55 D (SD ±0.51D) which was statistically significant (P<0.05). The mean 81Absolute PE in Immersion 0.625 D (SD ±0.346D) and in Contact 0,656 D (SD ±0.36D) which was statistically insignificant (P=0.735).The mean SE after surgery in Immersion -0.82 D (SD ±0.75D) and in Contact +0.016 D (SD ±0.55D) which was statistically significant (P=0.001).When comparing the target refraction -0.58D ±0.16D to refraction after surgery -0.82D ±0.75D in Immersion it was statistically insignificant (P=0.059), but in Contact the difference between the target refraction -0.53D ±0.12D and the refraction after surgery +0.016D ±0.55D was statistically significant (P=0.001)Conclusion: There was a significant difference in the PE between postoperative refractive errors obtained with Contact biometry and Immersion A-scan biometry. Based on the results of our study, the Immersion A-scan technique is recommended to obtain the target refraction after surgery.
