D Gatinel, G Debellemanière, A Saad, R Rampat.Theoretical Relationship Between the Anterior-Posterior Corneal Curvature Ratio, Keratometric Index, and Estimated Total Corneal Power. Journal of Refractive Surgery, 2023

Cet article est disponible en open access:

Theoretical Relationship Between the Anterior-Posterior Corneal Curvature Ratio, Keratometric Index, and Estimated Total Corneal Power | Journal of Refractive Surgery (healio.com)

 

Il concerne l’étude des liens entre puissance kératométrique, indice de réfraction, et rapport des courbures entre les faces antérieure et postérieure de la cornée. Il est possible, grâce aux équations publiées, de calculer la valeur de l’indice kératométrique « exact » ou « idéal », qui fait correspondre la puissance kératométrique avec la puissance cornéenne totale.  Ceci pourrait être utile à l’étude des erreurs de correction réfractive en chirurgie de la cataracte (formules de calcul de puissance d’implant).

 

In this work just published in the Journal of Refractive Surgery, equations have been formulated to determine the optimal keratometric index value, facilitating the keratometric power to align with the total Gaussian corneal power. These equations directly assess how corneal variables, such as the ant/post curvature ratio, affect the optimal keratometric index value. The use of these calculations may help to analyze the source of errors in IOL power calculation formulas.

    Hi, the good news is that there are firms out there, EXNER PRO HACKER being one of them, who carry the technical and legal expertise you need in-house I had a withdrawal issue with them and couldn’t get my funds when I initiated a withdrawal, They ask me to pay 20% upfront fees, I did and they asked for me. It’s not so good if everyone complains about a particular issue and nothing is been done to correct it, Except we use external recovery companies like EXNER PRO HACKER Before withdrawal issues are resolved. It’s fraud to just wake up and decide to block my account for no reason, why? they kept telling me stories about verifying my income. I was finally able to get my funds recovered with the help of EXNER PRO HACKER, You can use them if you are in such a situation. Available to you with just one email or call. For you and anybody else who wants to get their stolen bitcoins or recover any crypto, they have lost to scammers. Talk to them.

    Bonjour Dr,

    J ai un glaucome à angle fermé + astygmatie. J ai été opérée pour le glaucome ce qui a révélé un glaucome malin. J ai du subir le retrait du cristallin avec une vitrectomie.

    Avant l opération, les médecins m ont dit que je serai à coup sur presbyte et qu il serait possible de m enlever l astygmatie.
    Après l opération je suis finalement myope et toujours astygmate. Par ailleurs je percois des corps flottant.

    Est ce que le glaucome préexistant peut empecher l usage d un implant plutot qu un autre en l occurence conduire a rendre le patient myope plutot que presbyte ? De meme est ce que le glaucome peut rendre redhibitoire la correction de l astygmatie ? Concernant les corps flottant est ce normal meme apres une vitrectomie ?

    Merci pour votre retour

    How I Got My Husband back… Am so excited to share my testimony of a real spell caster who brought my husband back to me. My husband and I have been married for about 6 years now. We were happily married with two kids, a boy and a girl. 3 months ago, I started to notice some strange behavior from him and a few weeks later I found out that my husband is seeing someone else. He started coming home late from work, he hardly cared about me or the kids anymore, Sometimes he goes out and doesn’t even come back home for about 2-3 days. I did all I could to rectify this problem but all to no avail. I became very worried and needed help. As I was browsing through the Internet one day, I came across a website that suggested that Dr.Mahlangu can help solve marital problems, restore broken relationships and so on. So, I felt I should give him a try. I contacted him and told him my problems and he told me what to do and I did it and he did a spell for me. 48 hours later, my husband came to me and apologized for the wrongs he did and promised never to do it again. Ever since then, everything has returned back to normal. My family is living together happily again.. All thanks to Dr. Mahlangu If you have any problem contact him and I guarantee you that he will help you. He will not disappoint you. you can Whatassp:+27787390989
