TECNIS PureSee IOL
Johnson & Johnson · Ophthalmology · First EDOF IOL, no contrast-sensitivity warning
- Type
- Implant
- FDA route
- Premarket approval (PMA)
- Used by
- Cataract surgeons
Cataract patients have an EDOF lens option that, per its indications, improves intermediate visual acuity compared with an aspheric monofocal IOL while keeping distance acuity comparable, and whose labeling carries no warning on loss of contrast sensitivity. The company says it will be available in the U.S. later this year.
- What it is
- A purely refractive extended depth of focus (EDOF) intraocular lens implanted in the capsular bag during cataract surgery. It corrects aphakia after cataract removal and mitigates the effects of presbyopia by extending depth of focus.
- Indicated for
- Adults with less than 1 diopter of pre-existing corneal astigmatism in whom a cataractous lens has been removed, for primary implantation to correct aphakia; the Toric II models are for adults with 1 diopter or more of preoperative corneal astigmatism.
- What changes
- Compared with an aspheric monofocal IOL, the lens provides improved intermediate visual acuity with comparable distance visual acuity, and the company reports contrast sensitivity comparable to aspheric monofocal controls (differences of 0.3 log units or less).
- Evidence
- Design not reportedStudy not named in the releaseThe company reports that 97% of patients reported no very bothersome visual disturbances, and a 1.5-line difference in mean monocular distance-corrected near visual acuity at 6 months compared with TECNIS 1-Piece. Contrast sensitivity showed no clinically meaningful differences (0.3 log units or less) versus aspheric monofocal controls.The source does not describe a clinical study or its design. Common for cleared devices, which can rest on equivalence to a predicate.
- Watch for
- Safety and effectiveness have not been substantiated in pregnant women, patients under 22, or those with preexisting ocular conditions or intraoperative complications listed in the labeling. Autorefractors may not give optimal postoperative refraction (manual refraction is recommended), the lens is for capsular bag placement only, and toric misalignment greater than 30 degrees may increase postoperative refractive cylinder.
