Mhlawumbi ukhe weva ngee-contact lens, okanye mhlawumbi ukhe wazisebenzisa. Uninzi lwexesha, sizibona njengeelensi ezincinci, ezithambileyo ezilingana kakuhle phezu kweliso elimnyama. Kodwa ubusazi na ukuba abanye abantu abaneengxaki ezithile zamehlo abanakunxiba iilensi eziqhelekileyo? Namhlanje, siza kuthetha ngohlobo olwahlukileyo kancinci, olukhethekileyo lwelensi olunokunceda kwiimeko ezinjalo. Ezi zibizwa ngokuba ziilensi ze-scleral.
Ngoko ke zithini iilensi ze-scleral?
Ngamafutshane, iilensi ze-scleral zikwaluhlobo lwelensi yokunxibelelana enxitywa elisweni. Nangona kunjalo, zinkulu kancinci kuneelensi zokunxibelelana ezithambileyo esihlala sizibona. Kwaye umahluko omkhulu kukuba aziphumli ngqo kwindawo emnyama ebuthathaka yeliso (i-cornea).
Khawuthelekelele ukuba i-cornea yeliso lakho ifana nenduli encinci, engqukuva. Ilensi eqhelekileyo ihleli phezu kwale nduli. Kodwa ilensi ye-scleral ihleli phezu kwale nduli kwaye iphumle kwinxalenye emhlophe ejikelezileyo yeliso (i-sclera). Yiyo loo nto ibizwa ngokuba yilensi "ye-scleral".
Kudalwa umsantsa omncinci phakathi kwale lensi kunye ne-cornea. Lo msantsa awushiywanga nje apho. Ngaphambi kokuba sifake le lensi esweni lakho, siyizalisa ngesisombululo esikhethekileyo se-saline (i-saline engenazo izithinteli). Okwenzekayo kukuba lonke ixesha uyinxibile, i-cornea yakho intywiliselwa kwesi sisombululo. Ifana nentlanzi encinci emanzini. Oku kunika isiqabu esimangalisayo, ukufuma, kunye nokukhusela iliso.
Ezi zenziwe ngezinto ezikhethekileyo eziqinileyo kancinci, kodwa ezivumela ioksijini ukuba idlule. Ngokwezonyango, ezi lensi sizibiza ngokuba yi-'Rigid Gas-Permeable' (RGP). Ngenxa yokuba azitshintshi imilo, zinokubonelela ngombono ocacileyo nakubantu abane-corneas ezimile ngendlela engaqhelekanga.
Enye into kukuba ngenxa yokuba ezi lensi zinkulu, imiphetho yazo iphantsi nje kweenkophe. Ngoko ke azinakwenzeka ukuba ziwe lula njengeelensi eziqhelekileyo, kwaye akukho thuba lincinci lothuli nezinye izinto ezingena elisweni.
Ziziphi iimeko apho kusetyenziswa khona iilensi ze-scleral?
Iingcali zamehlo zicebisa iilensi ze-scleral njengonyango lweemeko ezahlukeneyo. Ngamanye amaxesha zisetyenziselwa ukulungisa iingxaki zokubona ezingenakulungiswa ngeeglasi okanye iilensi zokunxibelelana eziqhelekileyo.
Makhe sibone kwitheyibhile engezantsi ukuba zeziphi iintlobo zabantu ezi lensi eziluncedo kakhulu kubo.
| Imeko okanye unobangela | Ingcaciso elula |
|---|---|
| Izifo zeCorneal | Ezi zisebenza kakhulu kwiimeko ezifana neKeratoconus , apho i-cornea iphuma phambili ikwimo yekhowuni. Nangona iilensi eziqhelekileyo zingafanelekanga emehlweni anemilo engalinganiyo, iilensi ze-scleral zibonelela ngombono ocacileyo. |
| Iliso Elomileyo Eliqatha | Abo badla ngokuba namehlo omileyo nacaphukileyo, ulwelo olungaphakathi kwezi lensi lunokugcina amehlo abo emanzi imini yonke. Oku kunika isiqabu esikhulu. |
| Iimpazamo Ezinzima Zokuhombisa | Ezi lensi zinokubonelela ngemibono ecacileyo kubantu abanamandla aphezulu abangenakulungiswa ngeeglasi zamehlo eziqhelekileyo okanye iilensi zoqhagamshelwano. |
| Ukonakala komphezulu weliso ngenxa yezinye izifo | Ezi lensi zinokunceda ekukhuseleni amehlo kwiimeko ezinzulu ezifana neGraft vs. Host Disease (GvHD) kunye neStevens-Johnson Syndrome, ezinokubangela umonakalo omkhulu kumphezulu weliso. |
| Ukuvaleka kweCorneal | Ukuba umphezulu we-cornea unamabala kwaye awulingani ngenxa yokwenzakala kweliso, ezi lensi zinokulungisa umphezulu kwaye zibone ngokucacileyo. |
| Ukufaka amayeza emehlweni | Ngamanye amaxesha, iyeza kufuneka linxibelelane nomphezulu weliso ixesha elide. Kwimeko ezinjalo, iyeza lingaxutywa nolwelo oluzalisa ilensi lize lisetyenziswe esweni. |
Ziziphi iingenelo zezi lensi ze-scleral?
Zininzi iingenelo zokusebenzisa ezi lensi, yiyo loo nto oogqirha bezincoma kwiimeko ezikhethekileyo.
- Umbono ocacileyo nobukhali: Neengxaki zokubona ezinzima ezingenakulungiswa ngeelensi ezithambileyo eziqhelekileyo zinokulungiswa ngezi lensi ze-RGP. Abantu abaninzi bathi umbono wabo ucacile kwaye ubukhali xa benxiba ezi lensi.
- Azihambi lula ngaphakathi kweliso: Ngenxa yokuba ezi lensi zinkulu kwaye imiphetho yazo iphantsi kweenkophe, akufuneki ukhathazeke ngokuba ziyawa nokuba ubaleka, utsiba, okanye udlala imidlalo.
- Ukhuseleko olukhulu lwamehlo: Ekubeni ezi lensi zigubungela indawo enkulu yeliso, zibonelela ngokhuseleko olungcono kwizinto zangaphandle ezifana nothuli nomoya.

- Utyando lunokuphetshwa: Abantu abaneemeko ezifana ne-keratoconus enzima banokufuna utyando lokufakelwa i-cornea. Nangona kunjalo, ukusebenzisa iilensi ze-scleral kunokulibazisa okanye kuphelise olo tyando.
Ngoko ke akukho zingxaki kule nto?
Njengayo nayiphi na into, ezi lensi zinokuba neengxaki zazo kunye neengxaki. Kodwa eyona nto ingcono kukuba uninzi lwazo lunokuphepheka kwaye lulawuleka.
- Kuthatha ixesha ukuqhela: Ngenxa yokuba ezi lensi zinkulu, zisenokubonakala kunzima ukuzinxiba, ukuzikhulula, nokuzicoca ekuqaleni. Kungathatha iveki okanye ezimbini ukuqhela. Ugqirha wakho uza kukucebisa ukuba uzinxibe iiyure ezimbalwa ngosuku ekuqaleni uze wongeze kancinci ixesha olinxibayo.
- Ibiza kancinci: Xa kuthelekiswa nee-contact lens eziqhelekileyo, ii-scleral lens zibiza kancinci. Oku kungenxa yokuba aziyonto unokuyithenga evenkileni. Kufuneka zilinganiswe ngokukodwa emehlweni akho kwaye zenziwe zilingane nawe.
