The ll-79 lidofilcon b contact lens was cleared by the FDA via PMA P840031 on July 9, 1998. Manufactured by Lombart Lenses, it is classified as a Class 3 device.
What It Is
The ll-79 lidofilcon b is a hydrophilic contact lens designed for extended wear, primarily used in aphakic patients. It is steam sterilized and intended to improve visual acuity.
Clinical Applications
Commonly used in aphakic patients, this lens provides an alternative to spectacles for extended wear. It is particularly useful in cases where traditional corrective lenses are not suitable.
Evidence Summary
The literature includes two studies from 1983, involving a total of 437 eyes. These studies evaluate the lens's efficacy and safety in extended wear scenarios.
Reported Outcomes
Published studies report that the ll-79 lidofilcon b lens successfully fitted in 89% of cases, with improved visual acuity in aphakic patients. Most patients achieved 'overcorrected' acuity of 6/12 or better.
Safety Profile
Reported complications include transient lens-related problems leading to discontinuation in some cases. Issues with fit, comfort, and infection were noted but not prevalent.
Evidence Limitations
The evidence is limited to studies from 1983, with no recent data available. Further research is needed to evaluate long-term outcomes and safety in diverse populations.
