Abstract Details

Purpose:

To evaluate the changes after Implantable Collamer Lens (ICL) implantation on high order aberrations (HOA) of the eye.

Setting:

Dunya Eye Hospital Istanbul Turkey

Methods:

30 eyes of 18 patients were included in this study. Refraction, HOAs (corneal, internal and total) were measured (iTrace, Tracey) pre and 3 months postoperatively. Dependent samples T-Test (SPSS, IBM) was used to disclosure differences in the results.

Results:

An dependent samples t-test revealed a statistically significant difference between spherical equivalent (t = -26,902, df = 29, p < .00001). Postoperative SE (M = -10.21, SD = 1.89) reported significantly lower than preoperative SE (M = 0.73, SD= 0.77). Statistical analysis revealed another significant improvement on HOAs RMS values. HOAs were analyzed as Corneal, Internal and Total. The difference between total HOAs (t = 3.82, df = 29, p < .0006) and internal HOAs (t = 2,89, df = 29, p < .0005) were significant. There was no significant change found on cornel HOAs as expected. The total HOAs decreased 0.15 (SD= 0.09) to 0.09 (SD=0.03) and internal HOAs decreased 0.16 (0.08) to 0.1 (SD=0.05).

Conclusions:

Statistical outcomes showed that ICL implantation not only corrected the refractive error but also decreased internal HOA and total HOAs of the eye.
