PMMA Intraocular Lenses

The gold standard against which all
other IOL biomaterials are measured

Having been in continuous use as an IOL biomaterial for over 60 years, PMMA (Polymethylmethacrylate) has the best safety record of all currently available IOL biomaterials.

• The first IOL biomaterial to give acceptable results
• Not adversely affected by UV light
• Maintains a smooth surface even when in contact with vascular or physically active tissue
• Not biodegradable within the eye
• Relatively inexpensive
• PMMA remains a standard implant material worldwide.

Only Rayner PMMA lenses offer the quality and performance demanded by today’s ophthalmologists.

• Manufactured from ultra-pure Perspex™ CQ UV
• Lathe-cut for consistency and quality
• Not characterised by “crazing” or “snowflake effect”
• Optically pure
  – No “glistening” or “vacuoles”, which have been associated with some modern hydrophobic acrylic biomaterials
  – No discolouration or “browning”, which has been associated with some silicone biomaterials.

Only Rayner PMMA lenses have stood the test of time.

• Rayner manufactured the World’s first IOL in 1949
• The longest history of any IOL manufacturer, worldwide.

Clinically-based evidence for the historical success of Rayner PMMA.
Follow-up of 3 patients with Ridley intraocular lens implantation
(Letocha and Pavlin, JCRS – Vol 25, April 1999).

• This clinical paper describes the success of 3 patients who received original Rayner Ridley PMMA lenses implanted in the 1950s
• “Also contributing to the success of the procedure were the quality controls imposed by the maker Rayner”.
