Purpose: To compare efficacy, safety and stability of Femtosecond assisted LASIK and implantable collamer lens implantation in correction of high myopia. Methods: This study was nonrandomized comparative prospective consecutive interventional study. It included 74 eyes with high myopia (≥ -6 Ds) of 40 patients attended to the outpatient ophthalmic clinic of Sohag university hospitals from the period from Jan.2016 to Jan.2017. The patients were divided into two groups depending on: Degree of myopia, corneal thickness and corneal tomography. The first group (34 eyes) of 20 patients were subjected to implantable collamer lenses implantation and the second group (40 eyes) of 40 patients were subjected to femtosecond assisted LASIK. Results: Group one (ICL group) showed UCVA preoperative was (1.90±0.29) and UCVA postoperative was (0.27±0.21) with (p-value<0.000*). BCVA preoperative was (0.526±0.272) and that of BCVA postoperative was (0.217±0.128) with (p-value<0.001*), which means that BCVA postoperative was better than what was expected from the BCVA preoperative. Spherical error decreased from (-13.576±3.945) preoperative to (-0.0385±0.821) postoperative with (p-value<0.000*).Cylindrical error preoperative was (-1.134±0.617) and postoperative was (-0.352±0.250) with (p-value<0.000*).Spherical equivalent preoperative was (-15.173± 4.079) and that of postoperative was (-0.269±0.787) with (p-value<0.000*). Pachymetry preoperative was (518.153±22.981) and postoperative was (521± 22.304) with (p-value <0.140). Group two (Femtosecond assisted LASIK) UCVA preoperative was (1.42±0.27) and UCVA postoperative was (0.366±0.21) with (p-value<0.000*).There wasnít significant difference between BCVA preoperative and postoperative. Spherical error preoperative was (-8.398±1.733) and postoperative (-0.796±1.186) with (p-value<0.000*). Cylinder error mean value preoperative was (- 1.648±0.838) corrected to (-0.765±0.423) with (p-value< 0.005). Spherical equivalent preoperative was (-9.213±1.899) and that of postoperative is (-0.935±1.11) with (p-value<0.000*). Pachymetry preoperative was (535.111±26.33) and postoperative (419.88± 43.063) with (pvalue<0.000*). Conclusion: Both implantable collamer lens and Femtosecond assisted LASIK proved high efficacy and safety but implantable collamer lens showed more stability for high myopic patients.
