Certain embodiments provide a method of performing ocular biometry. The method includes performing phacoemulsification to emulsify and remove an internal lens of an eye. The method further includes performing vitrectomy to remove vitreous from the eye. The method also includes placing a trial in a lens capsule of the eye. The method further includes performing biometry with a first biometry system to provide measurements including at least one of an axial length of the eye, a curvature of a cornea of the eye, and toric axis. The method also includes removing the trial from the lens capsule.
- Claim:
1. A method of performing ocular biometry, comprising: performing phacoemulsification to emulsify and remove an internal lens of an eye; performing vitrectomy to remove vitreous from the eye; placing a trial in a lens capsule of the eye; performing biometry with a first biometry system to provide measurements including at least one of an axial length of the eye, a curvature of a cornea of the eye, and toric axis; and removing the trial from the lens capsule.
- Claim:
2. The method of claim 1, further comprising: selecting an intraocular lens (IOL) based on the measurements; and implanting the IOL in the lens capsule after the trial is removed.
- Claim:
3. The method of claim 2, further comprising: performing biometry with the biometry system or another biometry system, subsequent to implanting the IOL.
- Claim:
4. The method of claim 1, further comprising: removing vitreous hemorrhage prior to placing the trial in the lens capsule.
- Claim:
5. The method of claim 1, further comprising: performing membrane peeling to address a vitreomacular disorder prior to placing the trial in the lens capsule.
- Claim:
6. The method of claim 1, further comprising: performing fluid-air exchange to replace fluids in the eye with air; and draining a sub-retinal fluid prior to placing the trial in the lens capsule.
- Claim:
7. The method of claim 1, further comprising: performing fluid-liquid perfluorocarbon exchange to replace fluids in the eye with liquid perfluorocarbon prior to placing the trial in the lens capsule.
- Claim:
8. The method of claim 1, further comprising: performing fluid-silicone oil exchange to replace fluids in the eye with silicone oil prior to placing the trial in the lens capsule.
- Claim:
9. The method of claim 1, wherein the first biometry system is configured to perform at least one of an intraoperative optical coherence tomography (iOCT), swept source biometry, and intraoperative aberrometry.
- Claim:
10. The method of claim 1, wherein the measurements are based on at least one of: a refractive index of a substance that fills the eye when the first biometry system performs the biometry, a curvature of the trial, and a refractive index of the trial.
- Claim:
11. A biometry system, comprising: a memory comprising executable instructions; and a processor in data communication with the memory and configured to execute the instructions to cause the biometry system to: receive an indication to perform biometry on an eye; perform biometry on the eye, wherein: the eye is aphakic; vitreous is removed from the eye; and a trial is placed in a lens capsule of the eye; and provide a set of measurements based on the biometry.
- Claim:
12. The biometry system of claim 11, wherein: the eye is filled with a substance including balance salt solution (BSS), air, gas, liquid perfluorocarbon, silicone oil, or an alternative vitreous substitute.
- Claim:
13. The biometry system of claim 12, wherein: the indication is indicative of information including at least one of: a refractive index of the substance that fills the eye when the biometry system is performing the biometry; a curvature of the trial, and a refractive index of the trial; and the biometry is based on the information.
- Claim:
14. The biometry system of claim 11, wherein vitreous hemorrhage is removed from the eye prior to the biometry.
- Claim:
15. The biometry system of claim 11, wherein membrane peeling is performed to address a vitreomacular disorder of the eye prior to the biometry.
