OSN Europe: Phakic lens offers new option for presbyopia correction

A novel posterior chamber phakic IOL may provide correction for presbyopia, as well as myopia and astigmatism. According to Luis Salvà Ladaria, MD, and Scott Anderson García, MD, ophthalmologists in Palma de Mallorca, Spain, it is “the missing link” within the options for presbyopia.
“We have, alone or in combination, several laser options, refractive lensectomy, corneal inlays and even eye drops, but a phakic IOL had not yet been proposed,” Salvà said in an interview with Ocular Surgery News.
The new Implantable Phakic Contact Lens (IPCL, Care Group) was designed by Indian engineers, based on extensive experience with the Visian ICL (STAAR Surgical). With more than 500,000 implantations performed worldwide in 20 years of commercial availability, the ICL has marked a milestone in IOL technology, providing solid evidence of safety, reversibility, ease of implantation, stability of results and ability to correct high ametropia.
“The IPCL emerges as a new twist to a well-established concept, with further improvements in terms of design, material, dioptric range and the entirely new multifocal option (IPCL Presbyopia),” Salvà said.
The lens
Made of hydrophilic acrylic material that is 100% porcine collagen free, the IPCL is designed to have six points of contact, instead of four, with the ciliary sulcus for improved stability. It has two positioning holes in the haptics to facilitate implantation and four holes in the optic periphery to allow aqueous flow without causing a disturbance to vision.
“Injection is easy and reproducible with a normal injector by Medicel. With ICLs, sometimes there are difficulties because the lens tends to turn upside down, but this lens is made of an acrylic material that is relatively harder and easy to handle into the eye and to place in the appropriate position,” Salvà said.
The IPCL Presbyopia has a diffractive optical zone of 3.5 mm in diameter, which allows a soft sliding of the iris over the lens and aims at reducing halos. It is available with additions between +1.5 D and +3.5 D, in steps of 0.5 D.
