He is highly myopic and first visited us wishing for cataract surgery with an extended depth of focus multifocal lens. He was already being treated with glaucoma eye drops at another clinic and had visual field loss, so lens types that reduce contrast sensitivity were ruled out. He also drives and plays sports, struck me as relatively particular about quality of vision, and did not have advanced medical care insurance, so we recommended MiniWELL Ready, which, like a monofocal lens, has almost no halos or glare. We aimed for micro-monovision with the non-dominant left eye at about −0.75 D, there was no postoperative refractive error, and as a result he was satisfied with very good vision of 1.5 distance / 1.0 near.
MiniWELL Ready is imported from SIFI in Italy, so it takes about a month from ordering, after the lens power is decided, to delivery. He was highly myopic with a risk of postoperative refractive error, so we decided and ordered the left eye's lens power after the right eye's postoperative refraction and vision had stabilized. The interval between the right and left eye surgeries was therefore about a month, but he also used a soft contact lens, so he lived without trouble from anisometropia.
At our clinic, when both eyes are operated on with multifocal lenses, we leave an interval of at least a week. This is to improve postoperative satisfaction by first hearing how the patient sees at distance and near after the first eye and deciding the other eye's target refraction according to their satisfaction. Of course we ask about the desired focal distance and choose the lens before surgery, but after surgery patients often notice other wishes or inconveniences. So I feel that having patients first experience actual vision after one eye, and then use that as the point of comparison, lets them express their wishes more concretely. Some people are reluctant to have a slight difference between the eyes, but hardly anyone has exactly the same power in both eyes even before surgery, and, except in special cases, the difference is small enough that you would not notice unless told, so please rest assured.
