PCO was classified into pearly, fibrous, and mixed types. Their uncorrected visual acuity (UCVA), corrected distance visual acuity (CDVA), intraocular pressure (IOP), evaluation of posterior capsule opacification (EPCO) scoring and root mean square values of HOA (total, coma, spherical, and trefoil) were measured using a wavefront aberrometer before and after LPC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Pearly, fibrous, and mixed PCO were observed in 89 (46.1%), 47 (24.4%), and 57 (29.5%) eyes respectively.

The total HOA was 0.48 \u00b1 0.47, 0.43 \u00b1 0.42, 0.37 \u00b1 0.34, and 0.76 \u00b1 0.53, the coma aberrations were 0.18 \u00b1 0.15, 0.18 \u00b1 0.14, and 0.19 \u00b1 0.19, spherical aberrations were 0.07 \u00b1 0.12, 0.09 \u00b1 0.12, and 0.05 \u00b1 0.06, whereas the trefoil aberrations were 0.35 \u00b1 0.44, 0.24 \u00b1 0.26, and 0.21 \u00b1 0.20, 15-day post-Nd:YAG LPC in pearly, fibrous, and mixed PCO respectively, all of which showed a significant reduction.
