Indlela yokukhetha iilensi ze-multifocal?

Ngokuqinisekileyo, kufuneka wenze oku kuphela emva kokubonisana neengcali kunye nenani leemviwo - i-parameter ye-cornea izimisele: i-pachymetry ye-optical, i-index of asphericity, indawo yesikhungo somfundi, ububanzi bayo, ububanzi. Ukongezelela, ukuhlolwa kwe-retina kunye neenkalo ezibonakalayo zenziwa, ukukhishwa kweenjongo kunye nokuzimelela kumgama ohlukeneyo kuyafunyanwa.
