  • Abstract
  • Look Inside

I developed new aspherical plano-convex lenses to be used for slitlamp fundus examination. The lenses are improvements on the original design by Bayadi and have the power of +58 cliopters. Particular attention has been paid to ensure clear and bright fundus image and to minimize astigmatism, coma and distortion through adop-tion of larger size, asphericity and multiple coating of the lens. The present models allow the use of very narrow slitlamp beam because of the sharp definition of the system.
