Lo mbandela ungowama-200 ka-Uday Devgan, ikholomu ye-MD ethi "Buyela kwiSiseko" kwi-Eye Surgery News. Ezi kholamu ziye zafundisa i-novice kunye noogqirha abanamava ngokufanayo kuzo zonke iinkalo zotyando lwe-cataract kwaye zibonelela ngoncedo oluxabisekileyo ekusebenzeni utyando.Ndingathanda. ukubulela kunye nokuvuyisana no-Uday ngegalelo lakhe kupapasho kunye negalelo lakhe ekufezekiseni ubugcisa botyando lwecataract.
Ekwindla ka-2005, ndaqala le kholamu "yokubuyela kwisiseko" ngokusebenzisana nabahleli be-Healio / Ocular Surgery News, ukuphonononga iziseko ze-cataract kunye notyando oluyi-refractive.
Ngoku, malunga neminyaka eyi-17 kamva, kwaye kwinani lama-200 kwiphephancwadi lethu lenyanga, utyando lwamehlo luye lwatshintsha kakhulu, ngakumbi utyando lwe-cataract. qho ngonyaka.
Oomatshini be-Phaco baye benza inkqubela enkulu kwi-jet kunye ne-ultrasonic energy delivery.Iindlela zangaphambili zaziyi-3 mm ububanzi okanye ububanzi, zisebenzisa i-gravity infusion kunye ne-modulation ye-ultrasound elinganiselweyo.Iomatshini banamhlanje ngoku banikezela ngokunyanzeliswa kokunyanzeliswa, ukubeka iliso loxinzelelo olusebenzayo, kunye nokumodareyitha kwamandla okuzinzile ngakumbi. amagumbi angaphambili.Iminyaka elishumi edlulileyo, saxubana kwi-phaco yezandla ezimbini ukuze sihlukanise ukunyuswa kwinaliti ye-phaco, eyayisetyenziswe ngaphandle kwe-silicone cannula. eyamkelwa eUnited States.Ngoku sibuyela kwi-coaxial ultrasonography, nangona i-incision encinci, phakathi kwe-2mm uluhlu.
Kwakukho ii-IOL ezininzi kwiinyanga ezingama-200 ezidlulileyo, kodwa uyilo lwazo lwalungenangqondo ngakumbi kunento esinayo namhlanje.Uyilo olutsha lwe-trifocal kunye ne-bifocal diffractive IOL lubonelela ngombono obanzi ngaphandle kweeglasi. , engazange ibe nozinzo lwe-hydrophobic acrylic IOLs esisebenzisayo namhlanje.Sikwanikezela nge-toric IOLs kwiidigri ezahlukeneyo kunye neentlobo ezahlukeneyo ze-IOL designs.Siye safikelela kwisigqibo sokuba encinci ayisoloko ingcono, kwaye thina' d kunokuba ube ne-IOL enkulu efuna i-2.5mm yokusika kunemodeli encinci ekufuneka idlule kwi-1.5mm cutout.Ielensi zobude obujongisiweyo ziyaqhubeka nokuvela, kwaye uyilo olutsha ukulungiselela ii-IOL lusendleleni (Figure 1). kwixesha elizayo, ukulungelelanisa iilensi ze-intraocular ziya kukwazi ukubuyisela umbono wolutsha ngokwenene kwizigulane zethu.
Ukusetyenziswa kwethu kweelensi ze-intraocular kuye kwaphucula kakhulu ukuchaneka kwe-refractive, okuye kwazisa utyando lwe-cataract oluyi-refractive ngaphambili.I-biometrics engcono, zombini imilinganiselo yobude be-axial kunye nemilinganiselo ye-refraction ye-corneal, iphucule kakhulu ukuchaneka kwe-refractive kwaye iqhubela phambili ngokucokisekileyo. kwindawo apho umbono wefomula enye engatshintshiyo iza kutshintshwa kungekudala ngeendlela zokubala eziguquguqukayo kunye neziphuhlayo kusetyenziswa i-crowdsourcing kunye nobukrelekrele bokwenziwa.Ngekamva eliza kujongana ne-biometer yamehlo, izigulana zinokuthatha imilinganiselo kumatshini omnye ngaphambi nasemva. utyando lwe-cataract ukuqokelela idatha yophuculo oluqhubekayo kwiziphumo ze-refractive.
Iindlela zethu zotyando ziye zahamba ixesha elide kwiinyanga ezidlulileyo ze-200. Nangona iziseko zokuhlinzwa kwe-intraocular zisekho, siye sakha phezu kwayo ukuze sifezekise iziphumo ezingcono kwizigulane zethu.Bonke oogqirha kufuneka bajonge iteknoloji yabo yangoku kwaye bavume ukuba indlela yabo. ukusebenza namhlanje kubhetele kunokuba kwakunjalo kwiminyaka eyi-10 eyadlulayo.Ii-laser ze-Femtosecond, ii-aberrometers ze-intraoperative, iinkqubo zedijithali zotyando, kunye ne-head-up 3D displays ngoku ziyafumaneka kumagumbi ethu okusebenza.Ukusetyenziswa kwe-IOL yegumbi langaphambili kuncipha ngeendlela ezininzi ezahlukeneyo zokukhusela. I-IOL ukuya kwi-sclera.Ngaphakathi kwee-subspecialties, iindidi ezintsha ngokupheleleyo zotyando ziye zaphuhliswa, ezifana notyando oluncinci lwe-glaucoma kunye ne-lamellar keratoplasty.Nokuba i-intraocular lens extractions, edla ngokusetyenziswa kwi-cataracts exinene kakhulu, iye yavela kwi-extractions ye-extracapsular eqhelekileyo (efuna ukuthungwa okuphindaphindiweyo vala isikere esenziwe ngesikere) kwincwadana yobuchule botyando bokusika ulwelwesi oluncinci, oluneempawu zeshelving ukusikwa ukuze kutywinwe ngcono ngexesha elincinci, kunye neesutures, ukuba zikhona.
Ndisakuthanda ukufumana ushicilelo olushicilelweyo lweNdaba zeHealio/Ocular Surgery kwidesika yam kabini ngenyanga, kodwa ndikwazifumana ndifunda ii-imeyile zeHealio phantse yonke imihla kwaye ndisoloko ndikhangela iinguqulelo ze-intanethi zopapasho endiluthandayo.Eyona nkqubela inkulu yokufunda ngotyando kufuneka ibe kukusetyenziswa ngokubanzi kwevidiyo, esinokuyonwabela ngoku kwiifowuni zethu kunye neetafile kwi-high-definition.Ngokuphathelele kulo mba, kwiminyaka eyi-4 eyadlulayo ndadala indawo yokufundisa yasimahla ebizwa ngokuba yiCataractCoach.com epapasha ividiyo entsha, ehleliweyo, ebaliswayo yonke imihla. (Umfanekiso 2) .Njengoko lo mbhalo, kukho iividiyo ze-1,500 ezigubungela zonke izihloko kwi-cataract operation.Ukuba ndiyakwazi ukugcina iinyanga ze-200, oko bekuya kuba malunga neevidiyo ze-6,000. Ndiyakwazi ukucinga ukuba ikusasa lotyando lwe-cataract luya kuba njani.
