Yemagetsi keratometer SW-100

Kuyerwa kwekupetwa kwenzvimbo yepamberi yekorneya ne keratometer kunogona kupa hwaro hwekusarudza rakakombama base curve yeiyo yakapfava yekuonana lens. Inogona zvakare kushandiswa kuongorora iyo corneal astigmatism kuburikidza nekeratometer kupa chirevo che optometry.

Iyo keratometer inoshandiswa kuyera kukamurwa kwemeridani yega yega kumberi kwenzvimbo yekona iyo inenge 3mm pakati, ndiko kuti, nharaunda yekukombama uye kupindika, kuti uone kana cornea ine astigmatism, astigmatism, uye axial kutungamira.

Iwo makiriniki mabasa e keratometer ndeaya anotevera:

1. Panguva yekukodzera kwema lenzi, iyo yakakomberedza lenzi inogona kusarudzwa zvinoenderana neredhiyo yekukomberedza kwemameridani makuru epamberi peiyo cornea yemutengi.

Mukusarudza iyo yakakomberedza lenzi, iyo curve yelensi yakaenzana kana kuti yakati kurei kupfuura iyo nharaunda yekukomberedza kwemameridani makuru epamberi peiyo cornea. Iyi fomula inotevera inogona kushandiswa kuwana:

BC = iyo chiyero cheiyo radii yekukomberedza kwemaviri akafanana perpendicular main meridians / 2 × 1.1

Semuenzaniso, iyo curvature radii yemaviri makuru meridians ayo akaenzana kune mumwe nemumwe anoyerwa kuve 7.6 uye 7.8.

BC = 7.6 + 7.8 / 2 × 1.1 = 8.47

2. Wongorora kuomarara kwema lenzi mushure mekupfeka.

Paunenge uchiyedza, ita kuti iye akapfeka abheneke. Kana iye akapfeka akanyatso kusakara, chiratidzo chekuona chichagara chakajeka uye chisina kuchinjika;

Kana ikapfekedzwa zvakasununguka, mufananidzo uchave wakajeka usati wabhenekera, uye mufananidzo uchave wakasviba pakarepo mushure mekubwaira, uye uchajekeswazve mushure mechinguva;

Kana yakapfekedzwa zvakanyanya, mufananidzo uchave wakajeka usati wabhenekera, uye blur ichadzorerwa kwechinguva.

3. Keratometer inogona kushandiswa kuona mwero we astigmatism, axial direction uye kusiyanisa mhando ye astigmatism.

Kana paine astigmatism mu optometry, shandisa keratometer kuti uone astigmatism, zvichiratidza kuti astigmatism ndeye intraocular astigmatism.

Kana paine astigmatism mu optometry, astigmatism inoonekwawo nekeratometer, uye iyo astigmatism yevaviri yakaenzana, uye axial direction yakafanana, zvichiratidza kuti astigmatism yeziso zvese corneal astigmatism.

Kana iyo astigmatism iri mu optometry haina kuenzana ne astigmatism inowanikwa ne keratometer uye axis haina kuenderana, zvinoreva kuti iyo astigmatism musanganiswa we corneal astigmatism uye intraocular astigmatism.

Kana pasina astigmatism mu optometry, shandisa keratometer kuti uone astigmatism, zvinoreva kuti madhigirii e corneal astigmatism uye intraocular astigmatism akaenzana, uye zviratidzo zvakatarisana, axis yakafanana, uye vaviri vanodzima kunze. Iyi astigmatism inogona kugadziriswa nechitenderedzwa lens.

4. Kune zvimwe zvirwere zvemukati, senge keratoconus uye keratoconus, keratometer inogona kushandiswa sehwaro hwekuongorora. Kuyerwa kwe keratometer kunodiwa pakuona mwero wekuisirwa usati waiswa mukati meiyo intraocular lens uye dhizaini uye mhedzisiro yekuongorora kweakasiyana maitiro ekuratidzira. Uye zvakare, iwe unogona kudzidza nezvekuvanzika kwemisodzi uye zvichingodaro.
