| Abstract | | Introduction: To assess visual function of the eyes with corneal astigmatism higher than 1D after cataract surgery and implantation of a singlepiece plate-haptic toric hydrophilic acrylic intraocular lens with hydrophobic surface six months postoperatively. Methods: Patients with cataracts and corneal astigmatism higher than 1D were included into this prospective study. Predictive axis of IOL was marked on the cornea, standard phacoemulsification cataract surgery was performed and single-piece toric hydrophilic acrylic intraocular lens with hydrophobic surface was implanted into the lens capsule.Corneal astigmatism was measured pre- and postoperatively. Best-uncorrected and corrected distance visual acuity and change in axis orientation of astigmatism were measured postoperatively. Results: 34 eyes of 26 patients were included into this study. Mean best distance-uncorrected visual acuity in logMAR was 0.07 (SD:0.11), mean best distance-corrected visual acuity was -0.01 (SD:0.06), mean astigmatism of the eyes was 0.47 D (SD:0.35). Mean corneal astigmatism pre and postoperatively, was 2.50 D (SD:1.60) and 2.47 D (SD:1.60), respectively. The astigmatism axis of the eyeshas changed on average 3.6⁰ (SD:3.3⁰). Conclusion: Patients with medium tohigh corneal astigmatism and implanted single-piece toric hydrophilic acrylic IOLs with hydrophobic surface have very good visual function six months postoperatively.

| Summary | | Izhodišče: Določiti vidno funkcijo oči z roženičnim astigmatizmom, večjim od 1D, po odstranitvi sive mrene in vstavitvi enodelne torične hidrofilne akrilneintraokularne leče (IOL) s hidrofobno površino in ploščatimi haptikami šest mesecev po operaciji. Metode: V prospektivno študijo so bili vključeni bolniki s sivo mreno in roženičnim astigmatizmom, večjim od 1D. Pred operacijoje bil izmerjen roženični astigmatizem, na roženico je bila označena predvidena os IOL, nato je bila s standardno fakoemulzifikacijo odstranjena sive mrena in vsajena torična enodelna hidrofilna IOL s hidrofobno površino v lečno kapsulo. Po posegu je bila določena najboljša nekorigirana in korigiranavidna ostrina na daleč, roženični in interni astigmatizem in spremememba osi astigmatizma. Rezultati: V študijo je bilo vključenih 34 oči (26 bolnikov). Srednja vrednost najboljše nekorigirane vidne ostrine v logMAR šest mesecev po operaciji je bila 0,07 (SD: 0,11), najboljša korigirana vidna ostrina pa -0,01 (SD:0,06) srednja vrednost celotnega očesnega astigmatizma jebila 0,47 D (SD: 0,35). Srednja vrednost roženičnega astigmatizma preoperativno je bila 2,50 D (SD: 1,60), pooperativno pa 2,47 D (SD: 1,60). Osastigmatizma oči se je v povprečju spremenila za 3,6⁰ (SD 3,3⁰). Zaključek: Bolniki s srednjim do visokim roženičnim astigmatizmom imajo po vstavitvi torične enodelne hidrofilne IOL s hidrofobno površino zelo dobro nekorigirano vidno ostrino šest mesecev po operaciji.
