Stopped early · Not applicable
Conditions studied: Cataract, Ophthalmoplegia, Ophthalmologic Complication

Who can join
Age: 30 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Active duty and DoD beneficiaries aged 30 years or older undergoing cataract surgery
- Corneal astigmatism ≥ 1.0 D and a surgical plan that includes a toric intraocular lens for astigmatism correction. (The lens used will be the TECNIS IOL. It will be used on label)
- No observed zonular or capsular problems prior to, or at the time of, capsular tension ring insertion
You may not qualify if…
- Patients undergoing cataract surgery who do not have corneal astigmatism ≥1.0 D.
- Any observed zonular or capsular problems prior to, or at the time of, capsular tension ring insertion.
- Pre-existing ocular conditions, including:Pre-existing ocular conditions, including:
- Pseudoexfoliation syndrome in one or both eyes
- Prior incisional ocular surgery
- Lens subluxation
- Poor dilation or inability to position at the slit lamp (making postoperative outcome measurements difficult or impossible)
- Plans for extensive travel or to move away during the postoperative evaluation period
- Other conditions that would influence the capsule or lens positioning
- Surgical plan to include other procedures at the time of initial cataract surgery, such as Limbal Relaxing Incisions (LRIs), Micro-Incisional Glaucoma Surgery (MIGS), etc.
