# Beregning fra optisk akselængdemåler

## IOL-Master beregning

En måde er at vælge linsen ud fra IOL-Masterens anbefaling ved at vælge knappen **IOL**.

I eksemplet er det højre øje, som er aktivt. Venstre øjes felter er derfor grå og dermed inaktive felter, som ikke kan vælges.

Ved flere målinger markeres den ønskede måling. De anbefalede linser vises med **>** eller **<**.

Felterne i forundersøgelsesbilledet vil blive udfyldt med den valgte linse og styrke.

## NÆSER algoritmen

{% hint style="info" %}
**Bemærk!** Indstillingen hertil vil skulle sættes op af EG Clinea Support.
{% endhint %}

En anden måde er at vælge linsen ved at vælge knappen **Beregn**.

Vælg denne hvis der arbejdes med Linseberegningsalgoritmer i selve EG Clinea, som er blevet lagt ind i systemet. Metoden er helt uden om IOL-Masterens beregninger. På nuværende tidspunkt findes kun beregninger for NÆSER algoritmen. Beregningerne medregner den målte præoperative kammerdybde (ACD).

* Valget i '*Linse*' resulterer i en visning af en tabel over linser og konstanter.
* '*Rx,ref*:' er målet for den ønskede visus efter operationen og ud fra dette foreslås linsen.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://manual.egclinea.com/katarakt/forundersoegelse_katarakt/beregning.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
