Finishing of modern posterior chamber intraocular lenses.
We performed specular microscopy to study the surface finishes of modern posterior chamber intraocular lenses from 12 manufacturers. Specular microscopy detected surface contamination, severe polishing marks, subtle irregularities of the lens surface, roughly finished optic edges, and irregular edges of positioning holes in many lenses. The results indicated that the finishes on modern intraocular lenses from several manufacturers were not satisfactory, and surgeons should reconsider the quality of intraocular lenses.
