Abstract Details

Purpose:

To analyze and compare the surface properties of different commercially available hydrophobic acrylic intraocular lenses (IOLs).

Setting:

Eye Clinic, University of Trieste, Italy

Methods:

Six different hydrophobic acrylic one-piece IOL models with the same dioptric power were studied and compared: Clareon® IOL (SY60WF, Alcon Inc, Forth Worth, TX, USA), Tecnis® IOL (PCB00; Johnson and Johnson Vision, Santa Ana, CA, USA), enVista® IOL (MX60, Bausch and Lomb Incorporated, Rochester, NY, USA), CT Lucia® IOL (601PY, Carl Zeiss Meditec, Jena, Germany), Vivinex iSert® IOL (XY1, HOYA Corporation, Singapore, Singapore) and iSert® IOL (251, HOYA Corporation, Singapore, Singapore). IOL surface topography was analyzed by means of atomic force microscopy (AFM). Surface contact angle (SCA) measurements using sessile drop method were performed to assess IOL wettability.

Results:

AFM analysis revealed the lowest surface roughness in Vivinex iSertâ IOL and Clareonâ IOL compared to the other models (p<0.05). No statistically significant differences regarding surface roughness were found between Clareon® IOL and Vivinex iSertâ IOL (p>0.05). SCA measurements showed the highest hydrophobicity in iSertâ IOL. The CT Luciaâ IOL revealed the lowest contact angle if compared to the other IOL models.

Conclusions:

AFM and SCA measurements of all IOLs tested, revealed that Vivinex iSertâ IOL and Clareonâ IOL exhibited the best topographic features. The smoothest and more regular surface of these new IOL models, may lead to a reduction of cellular adhesion and therefore to a lower incidence of PCO.
