Dr. Welsh states that he has gone into a strange field to learn the terminology used, and that the terms used throughout his paper are those which he encountered.

This paper deals with some of the elementary but serious problems of corneal contact lens fitting which are unique to the aphakic family of corneal contact lenses.

The development of the lenticular cut form of the corneal contact lens is what has made contact lenses become so successfully fitted in such strong-plus prescriptions as those that correct aphakic refractive errors.

The Figure demonstrates some of the specifications of this lenticular cut type of aphakic-powered corneal contact lens.

1. This is a corneal lens whose over-all diameter is 10.0 mm. Aphakic corneal lenses vary from 9.6 to 10.8 mm. in diameter—occasionally more or less than these dimensions.

2. The lenticular optic portion is 8.0 mm. here and varies from 7.0 to
