Lolu daba luyikholomu yama-200 ka-Uday Devgan, ka-MD ethi “Back to Basics” Yezindaba Zokuhlinzwa Kwamehlo.Lawa makholamu abelokhu efundisa abaqalayo kanye nabahlinzayo abanolwazi ngokufanayo kuzo zonke izici zokuhlinzwa kolwelwesi lwama-cataract futhi banikeza usizo olubalulekile ekuhlinzeni.Ngingathanda ukubonga nokuhalalisela u-Uday ngeqhaza lakhe ekushicilelweni kanye negalelo lakhe ekufezekiseni ubuciko bokuhlinza ulwelwesi amehlo.
Ekwindla ka-2005, ngaqala le kholamu “yokubuyela ezisekelweni” ngokubambisana nabahleli be-Healio/Ocular Surgery News, ngibuyekeza izisekelo ze-cataract kanye nokuhlinzwa kwe-refractive.
Manje, cishe eminyakeni engu-17 kamuva, futhi ngenombolo engu-200 kumagazini wethu wanyanga zonke, ukuhlinzwa kwamehlo kuye kwashintsha kakhulu, ikakhulukazi ukuhlinzwa kwe-cataract refractive.Ukuphela okungaguquki okubonakala kuhlala njalo ekuhlinzweni kwamehlo kuwushintsho, njengoba amasu nezindlela zethu ziqhubeka nokuguquguquka. minyaka yonke.
Imishini ye-Phaco yenze intuthuko enkulu ekulethweni kwejethi kanye ne-ultrasonic energy.Izindlela zangaphambilini zaziyi-3 mm ububanzi noma ngaphezulu, zisebenzisa ukufakwa kwamandla adonsela phansi kanye nokuguquguquka kwamandla okulinganiselwe kwe-ultrasound.Imishini yesimanje manje ihlinzeka ngokufakwa okuphoqelekile, ukuqapha kwengcindezi esebenzayo, kanye nokuguquguquka kwamandla okuthuthukisiwe ukuze kuzinze kakhudlwana. amagumbi angaphambili.Eminyakeni eyishumi edlule, sadlala i-phaco yezandla ezimbili ukuze sihlukanise ukumnika inaliti ye-phaco, eyayisetshenziswa. ngaphandle kwe-silicone cannula.Yize lokhu kuvumela ukusetshenziswa kokusikeka okubili, ngakunye okungaphansi kuka-2mm ububanzi, akuzange kusetshenziswe kabanzi e-United States. Manje sibuyela emuva ku-coaxial ultrasonography, nakuba ngokusikeka okuncane, phakathi no-2mm ububanzi. .Amasistimu ethu e-ultrasound manje ahlinzeka ngokuphepha okungakaze kubonwe kanye nokunemba kokuhlinzwa kwe-cataract.
Bekunama-IOL amaningi ezinyangeni ezingu-200 ezedlule, kodwa amadizayini awo abengaqinile kunalokhu esinakho namuhla.Amadizayini e-IOL amasha e-trifocal kanye ne-bifocal diffractive ahlinzeka ngobubanzi obubanzi bokubona kahle ngaphandle kwezibuko.Esikhathini esidlule, ama-toric IOL ayeklanywe ngokuyinhloko ngama-silicone sheet haptics. , ebingenakho ukuzinza kwama-hydrophobic acrylic IOLs esiwasebenzisayo namuhla.Siphinde sinikeze ama-toric IOL ngamadigri ahlukahlukene futhi imiklamo ehlukahlukene ye-IOL.Sifinyelele esiphethweni sokuthi encane ayihlali ingcono ngaso sonke isikhathi, futhi singathanda ukuba ne-IOL enhle edinga ukusika okungu-2.5mm kunemodeli encane edinga ukunqamula i-1.5mm cutout. Amalensi anwetshiwe obude bokugxila ayaqhubeka nokuguquguquka, futhi imiklamo emisha yokufaka i-IOL isendleleni (Umfanekiso 1). Ngokuzayo, ukulungisa amalensi e-intraocular kuzokwenziwa. sikwazi ukubuyisela umbono wobusha ngempela ezigulini zethu.
Ukusebenzisa kwethu amalensi e-intraocular kuye kwathuthukisa ngokuphawulekayo ukunemba kwe-refractive, okulethe ukuhlinzwa kwe-cataract refractive ngaphambili.I-biometrics engcono, kokubili ezilinganisweni zobude be-axial kanye nezilinganiso ze-corneal refraction, ithuthukise kakhulu ukunemba kwe-refractive futhi iqhubekela phambili ngokuhlelwa okungcono.Manje sikhona manje. endaweni lapho umqondo wefomula eyodwa emile uzothathelwa indawo khona ishothi eliguqukayo neliguqukayo Izindlela zokubala zisebenzisa i-crowdsourcing kanye nobuhlakani bokwenziwa.Nge-biometer yamehlo ezilinganisa ikusasa, iziguli zingathatha izilinganiso emshinini ofanayo ngaphambi nangemva kokuhlinzwa kwe-cataract ukuze ziqoqe idatha yokuthuthukiswa okuqhubekayo emiphumeleni ye-refractive.
Izindlela zethu zokuhlinza ziye zahamba ibanga elide ezinyangeni ezingu-200 ezedlule. Nakuba izisekelo zokuhlinzwa kwe-intraocular zisekhona, sakhe phezu kwayo ukuze sizuze imiphumela engcono ezigulini zethu.Bonke odokotela abahlinzayo kufanele babheke ubuchwepheshe babo bamanje futhi bavume ukuthi indlela abahlinza ngayo ukusebenza namuhla kungcono kunaseminyakeni eyi-10 edlule.Ama-laser e-Femtosecond, ama-aberrometers angaphakathi kokusebenza, amasistimu okuqondisa ngokuhlinzwa kwedijithali, kanye nezibonisi ze-3D zekhanda phezulu manje isiyatholakala emakamelweni ethu okuhlinza.Ukusetshenziswa kwama-IOL egumbi langaphambili kuncipha ngezindlela eziningana ezihlukene zokuvikela i-IOL ku-sclera.Ngaphakathi kwe-subspecialties, sekusungulwe imikhakha emisha ngokuphelele yokuhlinza, njengokuhlinzwa kwe-glaucoma ne-lamellar keratoplasty.Ngisho ne-intraocular. Ukukhishwa kwamalensi, okuvame ukusetshenziselwa ulwelwesi lwamehlo oluminyene kakhulu, kuvele ekukhishweni okujwayelekile kwe-extracapsular. (idinga ukuthungwa okuningi ukuze kuvalwe ukusika okwenziwe ngesikelo) ukuze kwenziwe amasu wokuhlinza i-cataract encane, efaka ukusikeka kwamasheluvu ukuze kuvalwe kangcono ngesikhathi esincane, kanye nokuthungatha, uma kukhona.
Ngisathanda ukuthola inguqulo ephrintiwe ye-Healio/Ocular Surgery News etafuleni lami kabili ngenyanga, kodwa futhi ngizithola ngifunda ama-imeyili e-Healio cishe nsuku zonke futhi ngivame ukuphequlula izinguqulo ze-inthanethi zezincwadi engizikhonzile.Intuthuko enkulu yokufunda ngokuhlinzwa kufanele kube ukusetshenziswa okugcwele kwevidiyo, esingakujabulela manje kumafoni namathebulethi ethu ngencazelo ephezulu.Mayelana nalokhu, eminyakeni emi-4 edlule ngakha isiza sokufundisa samahhala esibizwa nge-CataractCoach.com ishicilela ividiyo entsha, ehleliwe, elandisiwe nsuku zonke (Umfanekiso 2).Kusukela kulokhu kubhalwa, kunamavidiyo angu-1,500 ahlanganisa zonke izihloko ngokuhlinzwa kwe-cataract.Uma ngingagcina izinyanga ezingu-200, lokho kungaba amavidiyo angu-6,000.Ngingacabanga nje ukuthi kanjani emangalisayo ikusasa ukuhlinzwa ulwelwesi amehlo kuyoba.
