Assessment of a single-piece hydrophilic acrylic IOL for piggyback sulcus fixation in pseudophakic cadaver eyes

Abstract

The new IOL has large optic and overall diameters, smooth and undulating haptics, and a convex-concave optic profile. Results show that these characteristics minimize the possibility of interaction with the primary IOL and uveal tissues, decreasing the likelihood of optical aberrations and pigmentary dispersion.

Assessment of a new hydrophilic acrylic supplementary IOL for sulcus fixation in pseudophakic cadaver eyes

“…This explains why, as previously mentioned, the study lens exhibited a greater ILD than the Sulcoflex relative to the primary IOL in cadaver eyes. 23 Our current results did not demonstrate a correlation between ILD and severity of Soemmering's ring, and also no correlation of ILD with primary IOL thickness, which may be due to the relatively small sample size. In a similar cadaver eye study evaluating the Sulcoflex, the ILD appeared mostly dependent on the primary IOL, but it is not known if the correlation was strong as the thickness of the primary IOL was not measured in that study.…”

“…In our study, in all cases a satisfactory ILD was found (range: 0.34-1.24 mm). This distance is likely adequate to prevent opacification as our laboratory previously reported the Rayner Sulcoflex to have a smaller ILD of 0.23-0.78 mm also in cadaver eyes, 23 and to our knowledge there do not exist any reports in the literature of ILO with the Sulcoflex lens. Like the add-on lenses currently on the market, the study lens has a convex-concave configuration in order to maximize the ILD.…”

“…In a similar cadaver eye study evaluating the Sulcoflex, the ILD appeared mostly dependent on the primary IOL, but it is not known if the correlation was strong as the thickness of the primary IOL was not measured in that study. 23 By using the Soemmering's ring data and ILD data from the same above-mentioned Sulcoflex study, the correlation coefficient (r) was calculated as − 0.20.…”

Calcification of hydrophilic acrylic intraocular lenses associated with intracameral air injection following DMEK

“…We describe 2 cases of calcification after Descemet membrane endothelial keratoplasty (DMEK). 9 Of particular interest is that 1 of the calcified IOLs was a sulcus-fixated supplementary IOL [10][11][12] and the other was a hydrophilic acrylic IOL with a hydrophobic surface. 13 To our knowledge, these are the first described cases of calcification with these IOL designs.…”

Additive Intraokularlinsen, ein neues Konzept für die primäre Anwendung (Duett-Implantation) oder für die sekundäre Refraktionsoptimierung

“…Kahraman publizierte vielversprechende Ergebnisse mit der Rayner Sulcoflex ® IOL [1] und Gerten präsentierte sehr gute Ergebnisse mit der HumanOptics MS 714 PB ® Linse [2]. In einer In-vitro-Studie zeigte Werner für die Sulcoflex IOL sehr positive anatomische Ergebnisse [3].…”
