Spectacles for aphakia

Historical Significance: The first intraocular lens was implanted by Sir Harold Ridley in November 29 1949. Prior to that, and for a quite a few years afterward as IOLs gained popularity, post-cataract patients had their loss of the optical power of the crystalline lens corrected by high plus spectacles. This book is about the technical challenges of spectacles correcting aphakia following cataract extraction. It had a reprint in 1977 but by that time IOLs were routinely inserted during a cataract operation so the problems of aphakic spectacles became consigned to history. Dr. Robert Welsh MD, began private practice at the age of 26 in Miami, Florida with Dr. Bascom H. Palmer, during which time he began research in the development of better cataract spectacles and advanced contact lenses for aphakia. He founded the first Contact Lens International Congress in 1963 and in 1969, he followed up the innovative and successful meetings with the then famed Welsh Cataract Congresses. He has authored numerous scientific papers and six text books on these subjects. His inventions include the Welsh Four Drop Spectacles for Aphakia, Minimal Effective Diameter Types of Optical Centering for Cataract Spectacles, large and tiny hard contact lenses for aphakia,
