Purpose.

To investigate disk halo size changes produced by a glare source after surgical insertion of an implantable collamer lens with a central hole (ICL V4c) for myopia correction.

Methods.

In this prospective study, disk halo size and pupillary light response with a vision monitor were measured preoperatively and at 1 week, 1 month, and 3 months postoperatively.

Pupillary light response parameters included contraction amplitude, latency, duration, and velocity; dilation latency, duration, and velocity; and initial, maximum, minimum, and average pupil diameters.

Results.

Forty-two right eyes of 42 patients were enrolled.

Postoperative uncorrected distance visual acuity was better than or equal to 20/20 in all eyes.

Compared to preoperative values, disk halo size showed no significant difference at 1 week postoperatively (P>0.05) and then decreased significantly at 1 and 3 months postoperatively (both P<0.001).

Contraction amplitude and velocity, as well as dilation velocity, decreased significantly at all postoperative time points (all P<0.001).

Disk halo size at 3 months postoperatively was significantly correlated with initial (r = 0.446, P=0.003), maximum (r = 0.483, P=0.001), minimum (r = 0.425, P=0.005), and average pupil diameters (r = 0.474, P=0.002).

Conclusions.

After ICL V4c implantation, disk halo size was reduced in the short term.

Patients with smaller pupil sizes during pupillary response to light experienced smaller halos after ICL V4c implantation.
