Purpose:To evaluate the quality of the peripheral fundus images observed through prism–type vitrectomy contact lenses using a surgical microscope equipped with a variable cross–cylinder and variable direct vision prism (VCC/VDVP) system. Methods: Resolution test charts were placed on the peripheral fundus of porcine eyes after lens aspiration, intraocular lens implantation, and simple vitrectomy and were observed through prism–type contact lenses (30°– and 45°–prism vitrectomy lenses) with a surgical microscope (OMS–610, Topcon) equipped with a computer–regulated VCC/VDVP system. Aberrations were corrected with cylindrical lenses for astigmatism and variable prisms for chromatic aberrations in the surgical microscopy system., and observed fundus images were recorded in HDTV. Results: Aberrations that substantially degraded the quality of the peripheral fundus images were corrected by the VCC/VDVP system, and the resolution of the peripheral fundus observation during vitrectomy was markedly improved. Conclusions: The quality of the fundus images during vitreous surgery through prism–type vitrectomy contact lenses is improved substantially by the VCC/VDVP system.
