Using a contralateral eye study design, which prevented the influence of potential confounding factors, Effectiveness of the OK lens was proved. Myopic progression within a subject was excellent compared with no intervention.
Purpose:To compare the accuracy and clinical usefulness of various devices by measuring axial length, keratometry, and white-to-white. Methods: In 64 eyes of 56 cataract patients, axial length was measured using Galilei™, Lenstar ® , and A-scans, and keratometry was measured using Galilei™, Lenstar ® , and ARK. In 86 eyes of 74 cataract patients, white-to-white was measured using Galilei™ and Lenstar ® . Results:The average axial length measurements using Galilei™, Lenstar ® , and A-scans were significantly correlated (p < 0.001), but without a statistically significant difference (p = 0.611). The 95% agreement range was the smallest at 0.22 mm for the Lenstar ® and A-scans. The average mean K using Galilei™, Lenstar ® , and ARK were significantly correlated (p < 0.001), but without a statistically significant difference (p = 0.657). The 95% agreement range was relatively small at 1.83 D for Lenstar ® and ARK. The average white-to-white using Galilei™ and Lenstar ® were significantly correlated (p < 0.001), with a statistically significant difference (p = 0.011). The 95% agreement range was 2.20 mm. Conclusions: Axial length, keratometry, and white-to-white measured by different devices were highly correlated and were not statistically different; however, agreement was low between measurements. It is therefore important to consider these findings when using them equally.
Purpose:In the present study, we introduced and evaluated the effectiveness of eyelid margin splitting combined with cilia rotation suture performed in simplified steps resulting in minimized complications in diffuse trichiasis. Methods: A retrospective review of medical records was performed on 31 eyelids of 21 patients with diffuse trichiasis. The patients had trichiasis of more than 1/3 of eyelid margin and received eyelid margin splitting combined with cilia rotation suture at our hospital. The patients did not have eyelid or lid margin abnormalities and were followed up more than 6 months after surgical correction. A telephone survey of the surgical outcomes including cosmetic satisfaction and recurrence was conducted in patients who did not visit at postoperative 12 months. Success was defined as complete resolution of symptoms and acceptable cosmesis at final visit. Results: The patients included 2 males (3 eyes) and 19 females (28 eyes) with an average age of 54.5 ± 18.3 years (range, 19.2-82.4 years). The mean follow-up period was 15.3 ± 5.6 months (range, 10-35 months). Cornea or conjunctiva irritation symptoms by misdirected eyelash were resolved in all eyelids; 3 eyelids with recurred trichiasis required additional electrolysis to remove irritating cilia resulting in an overall success rate of 90.3%. Conclusions: For patients with diffuse trichiasis, an eyelid margin splitting combined with cilia rotation suture performed in simplified surgical steps showed excellent results resolving irritating symptoms with very low recurrence rate and high cosmetic satisfaction.

Purpose: We used anterior segment optical coherence tomography (AS-OCT) to measure the pterygial subepithelial invasion length and thickness before and after surgery, and to evaluate the corneal epithelium and the extent of astigmatism.Methods: This was a retrospective study. Ten eyes that underwent pterygial excision surgery were analyzed. We used corneal topographic data to assess astigmatism before surgery and employed AS-OCT to measure corneal epithelial thickness and the length of subepithelial invasion. We measured the relative pterygial length, width, and area on anterior segment photographs. Corneal topographic assessment and AS-OCT were repeated 1 month after surgery. Multiple regression and Pearson correlation analyses were used to analyze the relationships between normalization of astigmatism and the size and thickness of the excised pterygium.Results: The mean With-the-Rule proportion of preoperative astigmatism was 2.9 ± 2.3 D and the mean corneal epithelial thickness 269.60 ± 84.17 µm. The mean thickness of the excised pterygia was 210.73 ± 80.36 µm. Pterygial thickness was significantly associated with the extent of preoperative With-the-Rule astigmatism and the normalized With-the-Rule astigmatism after pterygial excision. These correlations were stronger than those of the relative pterygial length, width, and area. The mean subepithelial invasion length was 595.00 ± 310.32 µm.Conclusions: An increase in pterygial epithelial thickness influenced the extent of With-the-Rule astigmatism to a much greater extent than did the relative pterygial length, width, and area. AS-OCT measurement of the subepithelial invasion length identifies the required excisional area prior to surgery.
