It has helped me immensely with my work as an optometrist. I love that it can be used by myself or in conjunction with multiple other professionals for more accurate diagnoses and treatments. Some of its functions are quite difficult to use at times but once you become familiar they start feeling pretty natural. If I were to say anything about this software it would have to be all the features we have been able to utilize. I think if there was any criticism left over from my experience using Dexis it would probably be the fact that sometimes certain functions don't stay saved after being closed out (such as changing font sizes). The benefits far outweigh the negatives so I wouldn't hesitate to recommend! We utilize different aspects of this program when helping patients diagnose diseases such as macular degeneration, cataracts and glaucoma.
