Iimbali ziphambuka kumbono oqhelekileyo, njengokuba udibanisa kumfanekiso. Uninzi lwabantu baqhelana nemigqaliselo yokubukeka, ukujonga kwangaphambili, i-presbyopia, kunye ne- astigmatism . Ezi ziqwalaselwa njengento yokuqala yokulungiswa komsebenzi kwaye zenze u-85% wombono womntu wokungafezeki kombono. Nangona kunjalo, olunye uluhlu lweziphene zokubhaliweyo ezingakhange zifumane ingqwalasela enkulu kude kube kutshanje kulungelelaniso oluphezulu.
Wonke amehlo anokungenani ubuncinane bezinga eliphezulu lolawulo. Ezi zinyango ziyabonakala ngoku ngakumbi kuba ubugcisa buye lwaphuhliswa ukuba luyihlolisise kakuhle.
Izimpawu kunye neMpawu
Iso lisoloko luneenkalo ezahlukeneyo zokulungiswa okuphezulu kunye kunye. Ngamanye amaxesha kunzima ukukhupha iimpawu zomntu ngamnye ezinokuthi zibonise enye ingxaki. Ezinye izilungiso eziphezulu eziphezulu ziyakwazi ukuvelisa izikhalazo zesigulane ezifana:
- Glare
- Halos
- Impembelelo ye Starburst
- Imifanekiso yeMoya
- Ukuqhafaza
Izizathu
Ngesinye iso iliso lomntu livelisa ukuphazamiseka komfanekiso. Ezi ziphazamiso zibizwa ngokuba yizizabelo. Njengoko umbane wokukhanya udlulela kwinkqubo ye-optical, inombono ongaphambili. Kwilihlo eligqibeleleyo, isantya sokusasaza singaphazamiswanga kwaye siphumelele. Kwijiso ngokungapheleli, isantya sokutshatyalaliswa sichaphazeleka kwaye sinesimo esifana nesithathu. Ukwenziwa komyalelo wokuphakanyiswa okuphezulu kungabangelwa iikrubhula ezingavumelekanga kwi- cornea kunye ne-lens, ukuxhwala, ukunqunyulwa, amehlo anomileyo kunye nabafundi abaninzi kakhulu.
Ukuxilongwa
Ukulungiswa okuphezulu kulandelwa ngokuqhelekileyo ngu "Shack-Hartmann aberrometer." Le fowuni inyathelo elibhekise phambili kweso kwaye lifanisa neliso elingenalo ukuhlutha. Le mephu yokubhabhadiswa ibhekiselwa kuye ngokuthi "iprint fingerprint" yeso isoyiko kuba ihlukile kwaye ayifani nayiphi na inkqubo yomntu.
Ngokungafani nemilinganiselo yembono yendabuko, efuna igalelo elizimeleyo kwisigulane, i-aberrometer ithatha imizuzwana kuphela ukufumana imilinganiselo kwaye ayifuni ukuba ube negalelo lesigulane.
Unyango
Ulwazi lwe-aberration oluphezulu luye lwafumaneka iminyaka emininzi. Kuphela kwiminyaka embalwa edlulileyo ubuchwepheshe bekhampasi obude buqhube ngokwaneleyo, nangona kunjalo, ukuvelisa izilinganiso ezichanekileyo kunye nokuhlola. Ezinye iindidi zesiganeko esitsha esilungeleleneyo, iilensi zokudibanisa, i-intraocular lens implants, kunye nokulungiswa kombono we-laser-guided guiding can correct the loss-order aberrations. Kuya kuphinda kuvezwe ngakumbi malunga nokunyangwa kwama-aberrations aphezulu kwiminyaka embalwa ezayo, njengeteknoloji ebomvu ibonakala sengathi inezicelo ezininzi ekulungiseni umbono.
