Purpose: To compare the clinical outcomes of glistening-free intraocular lens (IOL) and conventional 1-piece aspheric IOL in implanted in-the-bag.
Methods: After phacoemulsification performed by a single surgeon, 2 different IOLs were implanted: enVista MX60 (glisteningfree 1-piece aspheric IOL) in 38 eyes (group A) and AcrySof IQ (conventional 1-piece aspheric IOL) in 46 eyes (group B). Glare symptom score (0-5) obtained by questionnaires, best corrected visual acuity (BCVA), Functional Acuity Contrast Test (FACT), posterior capsular opacity (PCO), glistening formation and spherical equivalent error were compared and analyzed preoperatively and 6 months and 12 months postoperatively.
Results: A statistically significant improvement of BCVA and contrast sensitivity postoperatively was observed in all groups. There was statistically significant increase of glistening in group B compared with group A. However, there was no significant difference of FACT scores of spatial frequency in A, B, C, D and E columns and glare symptom score (0-10) obtained by questionnaires 12 months after surgery. Spherical equivalent errors were -0.38 ± 0.27 D and -0.36 ± 0.28 D for groups A and B, respectively. PCO occurred in 2 eyes in group A and 4 eyes in group B.
Conclusions: EnVista MX60 IOL showed less glistening formation than AcrySof IQ IOL, however, there was no significant difference in terms of vision quality such as BCVA, FACT and glare symptom score at 12 months postoperatively.
