Surface light scattering from 1-piece hydrophobic acrylic intraocular lenses with hydroxyethyl methacrylate: contralateral observation for 7 years

Abstract

Quantitative and intraindividual comparison of surface light scattering up to 7 years postoperatively confirmed the suppression with Clareon IOLs: the slight increase suggested no risk up to 12 years after implantation.

One-year multicenter evaluation of a new hydrophobic acrylic intraocular lens with hydroxyethyl methacrylate in an automated preloaded delivery system

“…Experimental and clinical studies demonstrated that the new hydrophobic acrylic IOL with HEMA is free from glistenings and surface light scattering. [2][3][4][5][6][7] Large-scale clinical evaluation of this IOL, however, has not been reported.…”

Clinical outcomes of new multifocal intraocular lenses with hydroxyethyl methacrylate and comparative results of contrast sensitivity, objective scatter, and subjective photic phenomena

“…The difference in contrast sensitivity between the two groups was most noticeable (Table 2 ). This result was the most meaningful, and it was more prominent than the existing monofocal IOL study [ 9 ]. Although the measuring instrument was different in the previous study, the AULCSF was not statistically significant in either group for up to 7 years after surgery.…”

“…However, the average value was better in the CN group, and further research over a longer period of time is required. In the previous study, surface light scattering was less in IOLs with HEMA, and this difference increased as the follow-up period did [ 9 ]. As time passes, it is thought that similar results can be obtained with multifocal IOLs; this study was not expected to show a significant difference, due to our limited follow-up period.…”

“…Therefore, the water content was increased to 1.5%, and the clarity of the lens increased. The CNA0T0 IOL improves clarity and solves long-term problems, such as glistening and surface haze [ 9 , 10 , 14 ].…”

“…Recently, release of CNA0T0 (Clareon, Alcon, Fort Worth, Texas, USA) has provided an IOL that replaced phenylethyl methacrylate (PEMA) with hydroxyethyl methacrylate (HEMA) by improving the material technology that the manufacturer had previously maintained [ 9 , 10 ]. Using these advantages, a diffractive multifocal IOL CNWT (Clareon Panoptix, Alcon, Fort Worth, Texas, USA), which utilizes novel materials based on existing multifocal IOL optics, has become commercially available.…”
