Detailed Description
Spectacle independence is one of the main aims in modern cataract surgery. Although bilateral monofocal IOL implantation, aiming for emmetropia or low myopia, leads to high levels of patient satifsfaction in distance vision, spectacle dependence for reading and other near vision tasks is the usual result.
There are different techniques to reduce spectacle dependence, the most common one is the use of multifocal IOLs. However, a variable number of patients complain of problems, such as glare or haloes. It appears that multifocal IOL technology does lead to less satisfying results in patients with pre-operative myopia. These patients are used to very good near vision when taking off their spectacles. Many of these patients would prefer to keep their distance spectacles and ideally would like to function well at intermediate and near distance without glasses for e.g. reading and computer- or household work.
One option to enhance intermediate vision and to leave patients with good contrast sensitivity is the use of extended depth of focus (EDOF) IOLs. One example is the ACUNEX Vario AN6V with a near add of 1.50 D. In particular, this design provides improved vision at a distance of 66 cm and more. Additional key features of the low-add IOL include good contrast sensitivity for twilight vision, optimized depth of focus, and natural imaging quality and color sensitivity.
Another option to allow spectacle independence is (mini-)monovision. For some people, who are in need of intermediate and near reading vision most of the time, mini-monovision with one eye having intermediate (arms length) and one eye having near (reading) vision is a good option ("myopic monovision").
Hence, the aim of the study is to analyse intermediate and near vision outcomes in myopic patients with either EDOF IOLs or monofocal IOLs with mini-monovision.
124 eyes of 62 patients will be included into this study. According to randomization, 31 patients will receive the EDOF IOLs (Acunex Vario AN6V) bilaterally, whereas in the other 31 patients a monofocal IOL (Acunex AN6) with mini-monovision will be implanted bilaterally. Follow-Up visits will be 1 hour, 1 week, and 2 months after surgery. A slit lamp examination, autorefraction and subjective refraction as well as visual acuity testing, reading performance, stereo vision testing and defocus curve assessment will be performed at this visits.
