Abstract Details
Purpose:
Diffractive multifocal IOLs occupy a prominent place in the correction of presbyopia despite the induced loss in quality of vision. Successive design refinements were made to improve visual acuity at all distances and to better preserve vision quality. We evaluate visual performances achieved with a new trifocal diffractive hydrophobic IOL.
Setting:
University Hospital - Brest France
Methods:
Prospective, descriptive, single-center study that enrolled 20patients without ophthalmic pathology, presenting bilateral cataract (LOC III > 2 and OSI > 4) , and corneal astigmatism of less than 1 D. All patients were motivated for spectacle removal. They received bilaterally a trifocal IOL AcrySof IQ PanOptix © (Alcon). Refraction, visual acuities at 4m, 35 cm and 60 cm were assessed as defocus curve at 1 and 3 month mono and binocularly. Quality of vision was approached by questionnaire of life, vision quality and Raytracing
Results:
Target of emmetropia +/- 0.50 D was obtained in 96% of cases with a mean postoperative spherical equivalent of 0.3 D. No loss of best visual acuity was reported. Mean monocular vision was 20/25 at all distances. One patient was inexplicably myopised and received a surface photoablation three months later. The aberrometry found a mean total high order aberration of 0,157μ with essentially coma. No postoperative complications were reported. 60 % reported mild halos at night but 95% of patients would redo the surgery.
Conclusions:
This new concept of trifocality seems verify its clinical and theoretical interest would be able to offer a comfortable intermediate vision in addition to restoring the vision of near and far while favorably respecting the quality of vision. Larger series and extended follow-up will strengthen these encouraging results and stability.
