Purpose
To evaluate the utility of different devices using anterior-segment optical coherence tomography (Triton and Anterion) in the quantification and classification of the glistening in intraocular lenses (IOLs)
Setting
Cross-sectional study on a series of 572 eyes of 320 patiens who had undergone cataract surgery from months to years before, and came for a routine examination.
Methods
Each subject was examined firstly by Anterion and afterwards by Triton on the same day, after pupil dilation, identifying the presence of glistening or hyperreflective foci (HFR) in the central area of the IOL. The best-corrected visual acuity and the sensibility to contrast were also assessed. The degree of glistening was then classified into 4 categories. The correlation between the results with both devices was calculated. The correlation between the degree of glistening and the type of intraocular lens examined, as well as the time since surgery, was also evaluated
Results
In this series of 572 eyes, the average number of HFR was 27 (0-226). The intraocular lenses studied were SN60WF, TFNT00, SN6AT6, DFT0T5, SN60AT, CNWTTO, SN6AT3, Vivity toric 515, TFNT01, SA60AT, TFNT30, TFNT40, CNWTT3, MA60MA, TFNT50, TFNT60, CNWTT4, SN6AT4, SN6AT8, SN6AT5, SN6AT2, SN6AD1, DFT4T5, MN60MA, SN60D3, SA60D3, MB60MA, and Synchrony. In addition to glistening, opacification of the IOLs was classified into moderate (subtotal) or severe (the whole lens). Moderate opacification was identified in 13.6% of the IOLs, mostly in SN60WF, SA60AT, SN60AT, MA60MA SN60D3, SN6AT8 and TFNT00. Severe opacification was found in 9.6% of the IOLs, mostly in SN60AT, SA60AT, SN6AD1 and SN6AT6, The concordance between Anterion and Triton was good.
Conclusions
Triton and Anterion are both efficient ways to identify, quantify and classify IOL glistening. The both can also provide relevant information when evaluating the opacification of IOLs
