Summary
Using the Terry surgical keratometer during planned extracapsular cataract extraction (ECCE) may reduce postoperative corneal astigmatism. This prospective study found lower astigmatism in patients where the keratometer guided surgical decisions.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Corneal Physiology
Background:
- Postoperative corneal astigmatism is a common complication following cataract surgery.
- Accurate measurement and management of astigmatism are crucial for visual outcomes.
Purpose of the Study:
- To evaluate the impact of using a surgical keratometer on postoperative corneal astigmatism after extracapsular cataract extraction (ECCE).
- To compare outcomes between a group using the Terry surgical keratometer and a control group.
Main Methods:
- A prospective study of 720 cases undergoing planned ECCE with posterior chamber lens implantation.
- Patients were divided into two groups: Group I (Terry surgical keratometer used) and Group II (no postoperative measurements).
- Outcomes were analyzed for early and late postoperative corneal astigmatism.
Main Results:
- One surgeon demonstrated statistically significant lower keratometer readings in Group I compared to Group II.
- A higher percentage of cases in Group I achieved final corneal astigmatism of 2 Diopters or less.
- The Terry keratometer use was associated with improved astigmatism control in specific cases.
Conclusions:
- The use of the Terry surgical keratometer may help in reducing postoperative corneal astigmatism after ECCE.
- Surgical technique and surgeon experience are significant factors influencing astigmatism.
- Further investigation into optimizing keratometer use in cataract surgery is warranted.
