There is no national public database of the cataract surgery queue in SUS. The official report itself had to fall back on press research, which recorded more than 168,400 requests and an average wait of about four months.

Among people aged 60 or older, 34.6% reported cataracts: 17.2% between 60 and 64, 33.9% between 65 and 74, and 55.5% from 75 up. Women, 38.6%; men, 29.4%.

The surgery takes 20 to 45 minutes, is done under local anesthesia — awake, with no pain expected —, one eye at a time on separate days, with same-day discharge, no driving home, eye drops for about four weeks, and vision can take several days to improve.

A monofocal lens focuses one distance; a toric lens corrects astigmatism; multifocal and accommodating lenses widen the range of vision and reduce the need for glasses, and some people still need correction.

In refractive surgery: 99.5% of eyes ended up with uncorrected vision better than 20/40 and 90.9% within half a diopter of target; 1.2% declared themselves dissatisfied and about 6.3% needed a touch-up. Sight-threatening complications: 0.07% of eyes.

Absolute contraindications for refractive surgery include unstable refraction, keratoconus and other ectasias, insufficient corneal thickness, significant cataract, uncontrolled glaucoma, uncontrolled external or autoimmune disease, and unrealistic patient expectations. Pregnancy and breastfeeding are relative contraindications.

The optical measurement of the eye fails in 8% to 17% of eyes, with dense cataract as the most common cause. Dilation takes 20 to 30 minutes and blurs vision for 3 to 8 hours, sometimes up to 24.

The clinic's own numbers — surgeries per year, years on the street, Google rating and count, number of surgeons, consultation price, installments and the three patient accounts — were invented for this demonstration. None of them came from a record, a public listing or a real person.
No calculation at all: Alcance does not exist. Every other number on this page comes from a public source and is on this list, with its scope and its caveat.
