Comparison of Post-Cataract Astigmatism: Fakoemulsification vs. Small Incision Cataract Surgery (SICS)

Introduction

Astigmatism is a common problem that patients face after cataract surgery, which can significantly interfere with the sharpness of vision. The incidence of astigmatism is influenced by various factors, including the incision method used, sclera stiffness, and the age of the patient. Therefore, it is crucial to understand the factors that affect the amount of astigmatism and to compare the changes in post-cataract surgery astigmatism between different incision methods. This study aims to compare the changes in post-cataract surgery astigmatism between two incision methods: Skleral slices in the Small Incision Cataract Surgery (SICS) and Clear Corneal slices on fakoemulsification, with intraocular lenses.

Understanding Astigmatism and Cataract Surgery

Astigmatism is a refractive error that occurs when the cornea or lens of the eye is irregularly shaped, causing blurred vision at all distances. Cataract surgery is a common treatment for cataracts, which involves removing the cloudy lens and replacing it with an intraocular lens (IOL). However, astigmatism can occur after cataract surgery, which can significantly affect the quality of vision. The incidence of astigmatism after cataract surgery is influenced by various factors, including the incision method used, sclera stiffness, and the age of the patient.

Research Purpose

The purpose of this study was to compare the changes in the level of astigmatism that occurred after cataract surgery using two different incision techniques, namely SICS and fakoemulsification. By knowing this difference, it is expected to provide valuable information for practitioners in choosing the right operating method, so as to minimize the impact of astigmatism on the quality of the patient's vision.

Methodology

This study involved 60 patients undergoing cataract surgery with the installation of intraocular lenses between April and June 2012. Evaluation was carried out through a keratometry examination before surgery, as well as 2, 4, 6, and 8 weeks after surgery. Of the 60 patients, 30 people underwent fakoemulsification with Clear Corneal incision and 30 other patients underwent SICS with scleral slices. In both methods, no sewing on incision wounds was carried out.

Research Results

The results obtained indicate that in the Clear Corneal slice method, astigmatism ranges from 0.5 - 1.22 D, whereas in scleral slices, astigmatism ranges from 0.6 - 1.10 D. Average Astigmatism for the 2-week Fakoemulsification Group after surgery is 2,403 ± 1,258 D, 4 weeks to 2,056 ± 0.658 D, 6 weeks to 1,513 ± 0.477 D, and 8 weeks to 1,101 ± 0.425 D. On the other hand, the average Astigmatism SICS group 2 weeks after surgery is 2,020 ± 1,203 D, 4 weeks to 2,072 ± 0.698 D, 6 weeks to 1,687 ± 0.623 D, and 8 weeks after surgery is 1,354 ± 0.827 D. Statistical analysis shows that there is no significant difference between the average astigmatism of the two groups.

Conclusion

From the results of the study, it can be concluded that there was a decrease in the mean astigmatism in both incision methods, both Clear Corneal slices in fakoemulsification and scleral slices in SICS. Although statistically there is no significant difference between the two, the mean astigmatism in the Clear Corneal slices method tends to be lower. This gives a clue that the selection of operating techniques can affect the results of postoperative vision, and therefore, it is important for cataract surgeons to consider the method that best suits the patient's condition to improve optimal clinical outcomes.

Implications of the Study

The results of this study have significant implications for cataract surgeons and patients. The study suggests that the selection of operating techniques can affect the results of postoperative vision. Therefore, cataract surgeons should consider the method that best suits the patient's condition to improve optimal clinical outcomes. Additionally, the study highlights the importance of keratometry examination in evaluating the level of astigmatism after cataract surgery.

Limitations of the Study

This study has several limitations. The study was conducted on a small sample size of 60 patients, which may not be representative of the larger population. Additionally, the study only compared two incision methods, and it is unclear whether the results would be the same for other incision methods. Further studies are needed to confirm the findings of this study and to explore the effects of other incision methods on post-cataract surgery astigmatism.

Future Directions

The results of this study suggest several future directions for research. Further studies are needed to confirm the findings of this study and to explore the effects of other incision methods on post-cataract surgery astigmatism. Additionally, studies are needed to investigate the effects of other factors, such as sclera stiffness and patient age, on post-cataract surgery astigmatism.

Frequently Asked Questions (FAQs) about Post-Cataract Astigmatism: Fakoemulsification vs. Small Incision Cataract Surgery (SICS)

Q: What is post-cataract astigmatism?

A: Post-cataract astigmatism is a refractive error that occurs after cataract surgery, where the cornea or lens of the eye is irregularly shaped, causing blurred vision at all distances.

Q: What are the common causes of post-cataract astigmatism?

A: The common causes of post-cataract astigmatism include the incision method used, sclera stiffness, and the age of the patient.

Q: What are the two incision methods compared in this study?

A: The two incision methods compared in this study are Fakoemulsification with Clear Corneal incision and Small Incision Cataract Surgery (SICS) with scleral slices.

Q: What are the results of the study?

A: The results of the study indicate that in the Clear Corneal slice method, astigmatism ranges from 0.5 - 1.22 D, whereas in scleral slices, astigmatism ranges from 0.6 - 1.10 D.
