Tanthauzo: Phacoemulsification ndi njira yowopsa kwambiri ya opaleshoni ya cataract. Opaleshoni ya Cataract imagwiritsidwanso ntchito kubwezeretsa masomphenya mwa odwala omwe masomphenya awo akhala mvula kuchokera ku ziwalo , kugoba kwa diso la diso .
Lens ili pafupi ndi iris. Ndili ndi udindo wowonetsa kuwala pa retina, ndi kupanga mafano omveka bwino. Lens ili ndi mphamvu yosintha mawonekedwe, otchedwa malo okhala.
Pamene maso akutha, komabe diso limakhala lovuta ndipo limataya kuthekera kwake. Lens lonse lili mkati mwa kapule ya lens. Pamene maso akutha, zowonjezera zowonongeka zimachitika ndipo maselo akufa amaunjikira mu capsule ya lens, kuchititsa kuti disolo likhale mvula pang'ono. Kuwala komwe kawirikawiri kumayang'aniridwa ndi lens kumatayika kuzungulira chifukwa cha cloudiness, kotero masomphenya sali omveka bwino ndi lakuthwa.
Kodi kupangidwanso kwapadera kumachitika bwanji?
Panthawi yopanga mafuta, dokotala wa opaleshoni amachititsa kachipangizo kakang'ono pamphepete mwa cornea ndipo kenaka amatha kutsegula pamphuno yomwe imayendetsa penti. Pang'onopang'ono timapepala tomwe timapanga timapanga timeneti timakhala tating'onoting'ono. Chidacho chikugwedezeka pa liwiro la ultrasonic kupukuta ndipo pafupifupi kutaya minofuyo kukhala zidutswa ting'onozing'ono. Zagawozo zimachotsedwa kunja kwa capsule ndi chotsatira pa nsonga yafukufuku.
Pambuyo pochotsa lens particles, pulojekiti yotchedwa intraocular lens, yomwe imatchedwa kuti IOL, imayikidwa ndipo imaikidwa m'mapulosi a chilengedwe.
Amalowetsedwa kudzera m'kanyumba kakang'ono kamene kamangotuluka mkati mwa chubu. Mngeloyo ukangobweretsamo, umaonekera ndipo umakhala pamalo ake.
Phacoemulsification kawirikawiri imachitidwa opaleshoni yopita kuchipatala ndipo nthawi zambiri safuna chipatala. Ndondomeko ya opaleshoni ya cataract ikuchitidwa pansi pa anesthesia (malo odyetseratu mankhwala ozungulira).
Kodi nthawi yowonongeka ya phacoemulsification ndi iti?
Chombo chopangidwa mu cornea kawirikawiri sichimafuna kusunthira ndi kudzidinda. M'masiku ochepa chabe, mankhwalawa amachiritsa. Mankhwala a diso amatha kuperekedwa ndipo nthawi zambiri amakhala ndi mankhwala opha tizilombo, steroids, ndi mankhwala osagwiritsa ntchito steroidal odana ndi kutupa. Madonthowa amachepetsa kutupa komanso kupewa matenda. Maantibayotiki nthawi zambiri amasiya masiku 7-10. Steroid ndi osati steroidal anti-inflammatory imatengedwa pamasabata atatu mpaka 6 malinga ndi opaleshoni. Odwala ambiri ali ndi kusintha kwa masomphenya pafupifupi nthawi yomweyo ndipo masomphenya amatha kusintha bwino kuposa masabata 4-5.
Phacoemulsification inasintha njira yothandizira opaleshoni. Asanayambe kupangidwanso, madokotala opaleshoni amachotsa lens lonse ndi kapsule. Izi zinapangitsa kuti zikhale zovuta kuyika lenti ya intraocular. Lensulo la diso limapereka mphamvu yochulukirapo pa diso. Chotsatira chake, ngati mutachotsa kadoti, yomwe ili ndi lenti, wodwalayo akusiyidwa ndi mankhwala aakulu kwambiri "kuphatikizapo," omwe akuwoneka bwino. Ichi ndichifukwa chake, zaka zambiri zapitazo, pamene odwala anali atachotsedwa, anavala "magalasi a cataract." Magalasi a Cataract anali olemera, olemetsa ndi olemekezeka maso.
Pasanapite nthaŵi yaitali madokotala ochita opaleshoni anazindikira kuti anafunikira njira yabwino yowonjezeretsa kuikidwa kwa lens kotero kuti odwala sangafunikire kuvala magalasi oterowo, olemera kwambiri omwe amatha kuchitidwa opaleshoni. Odwala anali okondwa kukhala ndi cataract, koma osasangalala kwambiri kuti tsopano amayenera kuvala magalasi olemera, olemera.
Ndani anayambitsa njira ya phacoemulsification?
Dr. Charles D. Kelman, dokotala wa odwala, ndi dokotala wa opaleshoni ku New York, akudziwika kuti akupanga njira yoyamba yopangira mafuta. cha kumapeto kwa zaka za m'ma 1960 ndi 1970, opaleshoniyo anaipeza. Dr. Kelman amagwiritsa ntchito malingaliro osiyanasiyana komanso mapangidwe osiyanasiyana koma analingalira kuti atha kukhala pansi pa mpando wa mano kuti azitsuka mano ake ndi kutsuka kwambiri.
Chochititsa chidwi, ena mwa malingaliro oyambirira omwe iye anali nawo akuwonetsanso kachiwiri mu masiku ano opaleshoni ya cataract.
