Two brand new reports show contact lens wearers prefer the latest multifocal lens designs to their everyday contact lenses. Researchers delivered the results from these two studies at the latest Optometry's Meeting, which was put together by the American Optometric Association.
One of these studies tested Bausch & Lomb's new Ultra for Presbyopia lenses. The other looked into the Dailies Total 1, which is a water gradient daily disposable multifocal lens (DDMF).
Amazingly, around 90 percent of the people involved in these studies liked the new contact lenses over their regular contacts. Study authors note this is a great sign for the future of contact lens design, especially for presbyopia patients.
The study that used Dailies Total 1 looked at 534 patients from the USA, Canada, Europe, and Oceania. The mean age of participants was 52 and all participants were properly fitted for the new DDMF lenses.
Over half of the patients in this study were already wearing multifocal lenses. The rest of the participants were wearing either monovision or single-vision lenses.
Researchers told the participants to wear the new lenses for no longer than two weeks. Patients had to throw out the lenses every night before bed and put in a new pair in the morning.
After the two weeks were up, patients filled out a satisfaction report. 92 percent of patients said the DDMF lenses were more comfortable than their normal lenses. 81 percent said their eyes were far less dry at the end of the day. In total, 85 percent of respondents said they'd rather use the DDMF lenses over their old lenses.
The study for Bausch & Lomb's Ultra for Presbyopia I lenses used 608 patients with a mean age of 51. 468 participants wore contacts and the remaining 140 wore eyeglasses. Since Bausch & Lomb wanted to test out these lenses in real-world situations, they made sure every single participant had a job that required them to look at a computer screen for six hours per day.
Just like the other study, Bausch & Lomb sent out a questionnaire after their patients used the contacts for two weeks. The results were in many cases even higher than the DDMF study.
Interestingly, people who switched from eyeglasses to Bausch & Lomb's contacts had extremely favorable responses to the multifocal lenses. 94 percent of spectacle wearers said they preferred the multifocal contacts to their eyeglasses. This counters the idea that contact lens companies shouldn't try to convert people wearing eyeglasses.
Optometrists at the Optometry's Meeting were stunned with the results. Harmony Grinstead, an OD in Maryland, told reporters, "The most important thing for me is that patients did not have to keep coming back to get the right fit." She also said that she was impressed that all the satisfaction reports were well over 50 percent.
Some optometrists now want to see what these results look like in older patients. Omar Lenfesty, and OD in Pennsylvania, said a mean age of 51/52 is rather young for presbyopia patients. Most people get presbyopia over the age of 60.
Presbyopia, also known as age-related farsightedness, is a common disease that makes it difficult for patients to see objects close up.
