Late-onset angle closure in pseudophakic eyes with posterior chamber intraocular lenses

Secondary angle closure in a pseudophakic eye due to pupillary block, more than a decade following phacoemulsification, has not been reported. We managed a 75-year-old female presenting with sudden, painful diminution of vision and raised intraocular pressure in the right eye. The key finding was an almost flat anterior chamber with intraocular lens in normal position clinically as well as on ultrasound biomicroscopy. The posterior chamber was ballooned up by vitreous, which was cleared surgically to restore the anatomy. Meticulous clinical examination augmented by ultrasound biomicroscopy findings helped us to diagnose and manage this case for satisfactory intraocular pressure and visual outcome.

Abstract Background To compare the anterior surface roughness of two commercially available posterior chamber phakic intraocular lenses (IOLs) using atomic force microscopy (AFM). Methods Four phakic IOLs were used for this prospective, experimental study: two Visian ICL EVO+ V5 lenses and two iPCL 2.0 lenses. All of them were brand new, were not previously implanted in humans, were monofocal and had a dioptric power of − 12 diopters (D). The anterior surface roughness was assessed using a JPK NanoWizard II® atomic force microscope in contact mode immersed in liquid. Olympus OMCL-RC800PSA commercial silicon nitride cantilever tips were used. Anterior surface roughness measurements were made in 7 areas of 10 × 10 μm at 512 × 512 point resolution. The roughness was measured using the root-mean-square (RMS) value within the given regions. Results The mean of all anterior surface roughness measurements was 6.09 ± 1.33 nm (nm) in the Visian ICL EVO+ V5 and 3.49 ± 0.41 nm in the iPCL 2.0 (p = 0.001). Conclusion In the current study, we found a statistically significant smoother anterior surface in the iPCL 2.0 phakic intraocular lenses compared with the VISIAN ICL EVO+ V5 lenses when studied with atomic force microscopy.
