Further to my recent comments about the Visian Collamer lens, there has been a study looking at this lens.
This was recently also mentioned in Mivision.
Basically in this study, 41 eyes were followed for 8 years, looking at quality of vision, endothelial cell loss, stability of refraction, complications and cataract formation.
Cataract was found in just less than 5% and is known to be a potential risk. The patients that developed cataract however, had uneventful cataract surgery with good vision afterwards. No one lost vision. Endothelial cell loss was only 6.2% at 8 years.
The article highlighted how the ICL is a good option for patients instead of LASIK with good outcomes and few complications.
