Ubushakashatsi bwa Bifocal ntibukiri kumaso gusaza.Ku bana ba myopic bafite imyaka 7, lens ya contact nyinshi zifite ubushobozi bwo gusoma cyane birashobora kudindiza cyane iterambere rya myopiya, ubushakashatsi bushya bwerekanye.
Mu igeragezwa ry’imyaka itatu y’amavuriro y’abana bagera kuri 300, imiti yandikirwa ya bifocal hamwe n’ikirenga hafi yo gukosora akazi yatinze iterambere rya myopiya ku ijanisha rya 43% ugereranije n’icyerekezo kimwe.
Nubwo abantu benshi bakuze bari mu kigero cy'imyaka 40 bafashe igihe cyo kumenyera uburyo bwabo bwa mbere bwo guhuza amakuru menshi, abana bari mu bushakashatsi bakoresheje uburyo bumwe bwo kugurisha bworoshye bworoshye bwo guhuza ibicuruzwa nta kibazo bafite cyo kureba nubwo bafite ubushobozi bukomeye bwo gukosora. iyerekwa no "kongera" uburebure bwibanze kumurimo wegereye amaso yumukecuru.

Jeffrey Walling, umwarimu wa optometrie muri kaminuza ya Leta ya Ohio akaba n'umwanditsi mukuru w'ubwo bushakashatsi yagize ati: “Abakuze bakeneye indimi nyinshi zo guhuza abantu kubera ko batagishoboye kwibanda ku gusoma.”
Ati: “Nubwo abana bambara utuntu twinshi two guhuza amakuru, barashobora kwibanda, ni nko kubaha umurongo uhoraho.Biroroshe guhuza kuruta abantu bakuru. ”
Ubushakashatsi bwiswe BLINK (Lifike ya Bifocal kubana barwaye Myopiya), bwasohotse uyu munsi (11 Kanama) muri JAMA.
Muri myopiya, cyangwa kutareba kure, ijisho rikura riba rirambuye muburyo budahuje, impamvu ikaba ikomeje kuba amayobera. Ubushakashatsi bw’inyamaswa bwahaye abahanga ubushobozi bwo guhuza amaso kugira ngo bagenzure imikurire y’amaso bakoresheje igice cyo gusoma cy’ibice byinshi. kwibanda kumucyo imbere ya retina - urwego rwimyenda yumucyo inyuma yijisho - kugirango ijisho ridindira.
Waring, akaba n'umuyobozi wungirije ushinzwe ubushakashatsi mu ishuri rya Leta rya Ohio muri Leta ya Ohio, yagize ati: y'amaso, kubera ko myopiya iterwa n'amaso akura igihe kirekire. ”
Ubu bushakashatsi hamwe n’abandi bumaze gutera imbere mu kuvura abana ba myopique, Waring yavuze.Ibisubizo birimo lensisiti yo guhuza abantu benshi, lens ya contact zihindura cornea mugihe cyo kuryama (bita orthokeratology), ubwoko bwihariye bwibitonyanga byamaso bita atropine, nibirahuri byihariye.
Myopia ntabwo ari ikibazo gusa. Miyopiya yongerera ibyago byo kurwara cataracte, retinal detachment, glaucoma, na myopic macular degeneration.Ibihe byose birashobora gutera kubura iyerekwa, kabone nubwo haba ibirahuri cyangwa lensike yo guhuza.Hariho nibintu byubuzima bwiza - kutareba neza byongera amahirwe yo kubagwa laser kugirango ukosore neza iyerekwa kandi ntushobewe mugihe utambaye aligners, nkigihe ubyutse mugitondo.
Myopia nayo irasanzwe, yibasira kimwe cya gatatu cyabantu bakuru muri Amerika, kandi iragenda iba benshi - nkuko abahanga mu bya siyansi bemeza ko abana bamara igihe gito hanze kurenza uko babikoraga kera. Miyopiya ikunda gutangira hagati yimyaka 8 na 10 no gutera imbere kugeza kumyaka 18.
Walline amaze imyaka myinshi yiga ku mikoreshereze y’imikoreshereze y’abana kandi yasanze usibye kuba nziza mu iyerekwa, lens ya contact ishobora no guteza imbere kwihesha agaciro.
Ati: "Umwana muto muto wa myopique nize yari afite imyaka irindwi."Hafi ya kimwe cya kabiri cy’abana bafite imyaka 7 barashobora guhuza neza na lens, kandi hafi yimyaka 8 yose irashobora. ”

Muri uru rubanza, rwakorewe muri kaminuza ya Leta ya Ohio na kaminuza ya Houston, abana ba myopic bafite imyaka 7-11 bahawe amahirwe yo guhabwa rimwe mu matsinda atatu y’abantu bambara lens: monovision cyangwa imiti myinshi hamwe na diopter 1.50 yiyongera mu gusoma hagati cyangwa Ongeraho cyane 2.50 diopters.Diopter nigice cyo gupima imbaraga za optique zisabwa kugirango ukosore icyerekezo.
Nkitsinda, abitabiriye amahugurwa bafite impuzandengo ya diopter ya -2.39 mugitangira ubushakashatsi.Nyuma yimyaka itatu, abana bambaye lens zifite agaciro gakomeye ntibagize iterambere rya myopiya no gukura kwamaso.Mu kigereranyo, abana bambaraga cyane bifocals yakuze amaso 0,23 mm munsi yimyaka itatu kurenza abambaye iyerekwa rimwe.Icyerekezo giciriritse ntidindiza gukura kwamaso kurenza icyerekezo kimwe.
Abashakashatsi bamenye ko igabanuka ryikura ryamaso rigomba guhuzwa ningaruka zose ziterwa no gutuma abana bemera ubumenyi bukomeye bwo gusoma mbere yuko abana bakeneye uru rwego rwo gukosorwa.Hariho itandukaniro ryinyuguti ebyiri hagati yambara lens ya monofocal nabambara lens nyinshi mugihe kugerageza ubushobozi bwabo bwo gusoma inyuguti zijimye kumurongo wera.
Waring yagize ati: "Ni ugushaka ahantu heza." Mu byukuri, twasanze ko n'imbaraga nyinshi zongeweho zitagabanije cyane icyerekezo cyabo, kandi rwose ntabwo ari muburyo bw'ubuvuzi. "
Itsinda ry’ubushakashatsi ryakomeje gukurikira abitabiriye amahugurwa amwe, ribavura hamwe n’ibice bibiri bifatanye cyane mbere yo kubihindura byose.
Ati: “Ikibazo ni uko, dutinda gukura kw'amaso, ariko bigenda bite iyo tuyakuye mu kwivuza?Basubira aho bari barateguwe mbere?Kuramba kw'ingaruka zo kuvura nibyo tugiye gusuzuma ”, Walline..
Ubushakashatsi bwatewe inkunga n’ikigo cy’igihugu cy’amaso, igice cy’ikigo cy’igihugu cy’ubuzima, kandi giterwa inkunga na Bausch + Lomb, itanga ibisubizo by’ibisubizo.
