| Sumario: | Spyridon E Chalkiadakis, Georgios A Amariotakis, Efstratios A Parikakis, Vasileios G PeponisAthens Eye Hospital, 2nd Eye Clinic, Athens, GreecePurpose: A preliminary study in order to test the accuracy of the IOL Master in detecting axial eye length changes after laser-assisted in situ keratomileusis and to correlate the findings with the theoretical ablation depth.Methods: Pre- and postoperative axial eye length measurements were performed in 10 consecutive eyes that underwent laser-assisted in situ keratomileusis with the Alcon Ladar Vision excimer laser to treat myopic refractive errors ranging from -2.50 to -8.00 diopters of spherical equivalent (mean: -5.23 ± 1.30 D).Results: The preoperative axial eye length measurements ranged from 24.53 mm to 27.78 mm (mean: 25.80 ± 1.01 mm) and from 24.57 mm to 27.57 mm (mean: 25.68 ± 0.93 mm) 1 month after the operation. Preoperative and 1-month postoperative data showed a statistically significant difference (P <0.05).Conclusions: The IOL Master showed a decrease in the axial eye length measurements that was bigger than the theoretical ablation depth and did not correlate well with it. Such data need to be confirmed by a larger cohort of patients.Keywords: ablation, biometry, coherence, excimer, interferometry, keratomileusis, laser |
