I have found toric IOLs invaluable for managing astigmatism for my cataract patients. The online calculators are great, but do require you to be in front of a computer to choose the lens and don’t easily allow you to try different wound locations or astigmatic combinations. EyeToric allows you to dynamically change the wound position to see the effect on lens power and placement. For anyone who has worked at a hospital where not all toric powers are routinely stocked, occasionally the lens you want is not available, or you have enlarged the main wound and need to compensate for greater astigmatism – EyeToric has this covered. It is possible to change the predicted lens power and axis placement and see the effects this has on postop astigmatism. If you get an unexpected postop result you are able to determine if this is due to unexpected lens positioning or inaccurate preop Ks – useful in planning further surgery. I think the application is quite intuitive, particularly if you have used the online calculator. Feedback is welcome. ## Key features - Dynamic wound position adjustment - Lens power and axis placement prediction - Post-operative astigmatism analysis - Compensation for enlarged wounds - Analysis of unexpected surgical results ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | eyeToric OCR | $1.99 | one-time | | eyeToric Database | $14.99 | one-time | ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/eyetoric/id442408289/reviews.md ### 5/5 — Brilliant! *2014-04-15, version 1.1* Easy to use. Best on the market. ### 5/5 — Amazing *2012-10-30, version 1.1* This app was extremely helpful understanding an off axis T8 toric iol ### 5/5 — Great toric calculator *2012-09-18, version 1.1* This is an excellent piece of software which I use several times per week. It is much faster than the IOL company web calculators and allows you to see how varying wound position alters final astigmatism. ### 5/5 — Functional and useful *2012-07-26, version 1.1* The calculator works as promised, and is useful for on the go toric calculation. Not going to win any beauty pageants, but that's okay. Thanks for making this tool available! Note that it is by default more aggressive than the Alcon web based one; for a patient I tried it with recently, by recommending a T6 it targeted 0.05 dippers of residual cyl (a slight overshoot) rather than the 0.54 diopters the online calculator left in the original axis by choosing a T5. A slider lets you adjust residual cyl to your own threshold. ### 5/5 — Ophthalmologist *2011-12-26, version 1.1* Simply excellent. ## Frequently asked questions about EyeToric ### What is EyeToric used for? EyeToric is a medical application designed for ophthalmologists to assist in managing astigmatism for cataract patients. It helps predict post-operative astigmatism by allowing dynamic adjustments to wound position and lens power. ### How does EyeToric help with lens selection? EyeToric allows users to dynamically change wound position and explore different astigmatic combinations to see the effect on lens power and placement. This is particularly useful when specific toric powers are not readily available or when compensating for enlarged wounds. ### Can EyeToric help analyze unexpected surgical results? Yes, if you encounter an unexpected post-operative result, EyeToric can help determine if it's due to unexpected lens positioning or inaccurate pre-operative keratometry (Ks) readings, which is valuable for planning further surgery. ### Is EyeToric easy to use? The application is described as quite intuitive, especially for users who have prior experience with online calculators for toric IOLs. Feedback is welcomed by the developer to further improve usability. ### What devices does EyeToric support? EyeToric is supported on iPhone, iPad, and iPod devices, making it accessible for use in various clinical settings. ### What is the age rating for EyeToric?

Support for iphoneX Lens Database updated to most recent constants at http://ocusoft.de/ulib/c1.htm. Two databases are now available to update online at http://eyeapps.com.au/lensdata.txt (ULIB database) and a seperate toric database (http://eyeapps.com.au/toricdata.txt. It is possible for the user to point to their own databases (in JSON format). A tolerance arc is displayed to show the "wriggle room" for toric placement. Set at 1D of astigmatism (can be changed in app settings). Improved access to IOLMaster database. Multiple bug fixes. ### 2.0.1 — 2014-08-05 Fixed the issue where a comma used as the "decimal mark" is not interpreted correctly. ### 2.0 — 2014-07-31 The toric calculator now supports multiple formulas and multiple lenses pulled from the ULIB website http://www.augenklinik.uni-wuerzburg.de/ulib/c1.htm. It is possible to capture a printout from an IOLMaster and automatically enter user biometry. It is also possible to sync the user database from your IOLMaster to do the same. ### 1.1 — 2011-09-09 Rounding error corrected on the toric calculator. T2 lens incorporated. Will also work with HOYA Toric. "Best lens" toric algorithm is more accurate. Flipside info panel. Simple mode available on landscape rotation (for presbyopes!). Native iPad version included which has an SRK/T lens calculator built into landscape mode (features on the fly A-constant and Refractive outcome). Also has ACIOL and Sulcus lens predictors. If users wish to have this incorporated into the iphone version please provide feedback. ### 1.0 — 2011-06-25 No release notes. ## Apps similar to EyeToric | App | Rating | Price | Category | | --- | --- | --- | --- | | [Biotech Connect](https://appshunter.io/ios/app/biotech-connect/id1222575199) | — | Free | Medical | | [IOL Reference](https://appshunter.io/ios/app/iol-reference/id1626671895) | 4.7 (15) | Free | Medical | | [Soleko IOL Calculator](https://appshunter.io/ios/app/soleko-iol-calculator/id1491714928) | — | Free | Medical | | [Biotech Calculators](https://appshunter.io/ios/app/biotech-calculators/id1056021060) | — | Free | Medical | | [TOD National 2024](https://appshunter.io/ios/app/tod-national-2024/id6723904225) | — | Free | Medical | | [Easy Eye](https://appshunter.io/ios/app/easy-eye/id394384745) | 4.5 (4) | Free | Medical | ## More apps by Steve Colley - [eyeSnellen](https://appshunter.io/ios/app/eyesnellen/id575171210) All apps by Steve Colley: https://appshunter.io/developer/442408292 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
