Abstract Details
Purpose:
To report the observation of opacification of hydrophilic acrylic capsule-fixated intraocular lenses after implantation of sulcus-fixated supplementary intraocular lenses.
Setting:
Memira Eyecenter, private refractive surgery clinics in Norway, Sweden and Denmark.
Methods:
Retrospective case-control study of consecutive eyes previously submitted to refractive lens exchange (RLE) and implantation of hydrophilic acrylic trifocal intraocular lenses. The prevalence of opacified lenses in eyes with a sulcus supplementary IOL (cases) was compared to the eyes without (controls).
From a total of 54 816 hydrophilic acrylic trifocal intraocular lens implantations in the period Jan 2013 to March 2020, 323 had a sulcus supplementary IOL implanted (mean 13 months post-operatively). The reasons for implanting a supplementary lens were to correct the residual refractive outcome and/or negative dysphotopsia.
Results:
We observed a total of 11 opacified IOLs. The average patient age was 55 years and 63.6% were male.
IOL opacification was observed 31 months (6 to 48 months) after the supplementary lens implantation. The opacification occurred only in the primary in-the-bag lens. YAG capsulotomy had been performed in 4 eyes.
In the group without supplementary IOLs there were 54 493 eyes and 4 opacified lenses (0.007%). In the group with supplementary IOLs there were 323 eyes and 7 opacified lenses (2.17%). The association between supplementary IOL implantation and opacification of the hydrophilic trifocal IOL is statistically significant (P < 0.00001 Chi-square test).
Conclusions:
Hydrophilic intra-ocular lenses can present a higher risk for opacification when implanted with sulcus supplementary lenses when compared to eyes without it.
