How to make the docking of concave eye patients in femtosecond laser surgery more smoothly?丨ESCRS 2022

Editor's note: Femtosecond laser surgery in ophthalmology usually includes the links of docking, imaging, analysis and laser treatment. Docking is very important for surgery. During docking, the patient's eye is docked to the suction cone, which provides pressure to flatten the patient's cornea and fix it in the position of the laser treatment, which plays a key role in the success of the surgery. But people are different, and patients with different facial features may cause some troubles for treatment. How to make the anthropometric parameters of these patients more accurate and make the treatment more accurate is a problem that ophthalmologists have been discussing. The 40th European Society of Cataract and Refractive Surgeons Annual Conference (ESCRS 2022) was grandly opened on September 16, local time in Milan, Italy, presenting a wonderful cataract and refractive academic feast to the audience. During the conference, a related study conducted by Dr. Deeksha Rani et al. brought some enlightenment to everyone. Now let's walk into this study together. Difficulties encountered in ophthalmic femtosecond laser surgery During femtosecond laser surgery, improper docking is a major risk factor for intraoperative suction loss. Multiple docking attempts to achieve proper docking may increase the risk of dark spots, so ophthalmologists want to achieve good docking in a single attempt. However, novice surgeons often find it difficult to deal with patients with concave eyes whose prominent nose, prominent eyebrows, and narrow palpebral fissures interfere with docking. For this reason, Dr. Deeksha Rani et al. studied the facial contours of 97 subjects presenting to a refractive error clinic to determine the subjects' anthropometric parameters and to explore whether interventions are needed to improve single-attempt docking. Success rate. Research Methods The researchers asked subjects to sit comfortably on a stool with their backs straight and look directly at a fixed target 6 meters in front of them. Front and side images were taken from a distance of one meter from the subject. During the docking process, subjects marked as "normal" do not need to perform positioning operations, while subjects marked with "concave eyes" need to perform positioning operations. The total facial convexity of the subjects was measured using a full-face convexity screen protractor. The measurement method is shown in the figure below. The parameters measured on the side images of the two groups of subjects were compared. The ROC analysis of the total facial convexity was bounded by 133°. . Measurement method: Research results Dr. Deeksha Rani believes that the subject's side image can be taken, and the subject's total facial convexity can be measured through a screen protractor. Summary of the total facial convexity of most subjects who have difficulty in docking. This study on the details of femtosecond laser surgery has aroused the thinking of many ophthalmologists. Nowadays, femtosecond laser surgery has been popularized in many hospitals, and the surgical techniques of doctors have also improved. More and more mature, how to further improve the quality of surgery? The key lies in the details of the operation. I believe that with the continuous exploration of ophthalmologists, the technology of femtosecond laser surgery will become more and more perfect, bringing more good news to patients.
