Purpose: To compare the long-term outcomes of sutureless intrascleral fixation of the intraocular lens versus sutured scleral fixation.Methods: The authors retrospectively analyzed the medical records of patients who underwent intrascleral fixation of the intraocular lens using two different techniques: trocarcannula-based sutureless fixation and sutured scleral fixation. Clinical outcomes were compared before and 1-, 3-, 6-, and 12-month follow-ups after the operation.Results: A total of 51 patients were followed over a 12-month period after the operation, including 28 eyes in the sutureless group and 23 eyes in the sutured group. Best-corrected visual acuity and spherical equivalent values reached targeted values faster in the sutureless scleral fixation of the intraocular lens. However, no significant difference was observed between the two groups. For intraocular lens capture, there was a statistically significant difference observed in the incidence of postoperative complications, which was demonstrated by one eye in the sutureless group and seven in the sutured group (P = 0.009). To exclude the effect of corneal astigmatism, surgically induced astigmatism was calculated based on the astigmatism value 1 year after surgery. It was found that the sutureless technique significantly reduced the occurrence of astigmatism (2.43 6 1.42 vs. 1.65 6 0.94, P = 0.031). Conclusion:In a 1-year follow-up period, the trocar-cannula-based sutureless technique was reliable and effective. Sutureless fixation was associated with fewer postoperative complications and lower surgically induced astigmatism values than those with sutured fixation.
Purpose: To introduce cases of intraocular lens (IOL) malposition after sutureless intrascleral fixation.Methods: We retrospectively analyzed the medical records of patients who underwent sutureless intrascleral fixation. Cases with postoperative IOL requiring reoperation were analyzed further.Results: Of the 48 eyes that underwent sutureless intrascleral fixation of their IOL, seven eyes had postoperative IOL malposition and underwent reoperation (14.6%). There was no difference in the clinical results between the intravitreal (33 eyes) and intracameral (15 eyes) techniques, but IOL malposition requiring reoperation was more frequent in the latter (2 cases [6.1%] vs. 5 cases [33.3%], P = 0.024). In the 7 eyes that required reoperation, the visual acuity before reoperation was 0.9 ± 0.6 logMAR (20/159), whereas astigmatism was 24.8 ± 3.2 diopters. The visual acuity and cylindrical error improved to 0.1 ± 0.2 logMAR (20/25) and 22.4 ± 2.3 diopters, respectively, at 6 months after the secondary operation.Conclusion: In 14.6% of the patients who underwent sutureless intrascleral fixation of the IOL, IOL malposition developed and reoperation was performed. With the intravitreal technique, which uses a wider space than the intracameral technique, the frequency of postoperative IOL malposition could be reduced.RETINA 42:64-72, 2022S utureless intrascleral fixation (also called the "Yamane technique") of intraocular lenses (IOL) has evolved since Maggi first published it in 1997. 1 Recently, several studies have been published on the clinical outcomes of the sutureless technique. [2][3][4][5] In a relatively recent study conducted by our group, the sutureless technique emerged as an effective and reliable technique even when compared with the conventional suture technique. 6 The sutureless technique reduced the operation time, resulted in less inflammation after surgery, and allowed for sooner visual acuity recovery as well as less astigmatism.
Purpose To report the efficacy and safety of brolucizumab in the treatment of refractory serous pigment epithelial detachment (PED) secondary to polypoidal choroidal vasculopathy (PCV). Methods Twenty-six eyes of 26 patients were included. Intravitreal brolucizumab 6.0 mg was administered, followed by pro re nata (PRN) retreatment at monthly follow-ups. All patients underwent spectralis domain optical coherence tomography (SD-OCT), fluorescein angiography, and indocyanine green angiography before the first brolucizumab injection. SD-OCT was repeated at follow-up visits. The height and width of the serous PEDs, measured using SD-OCT, were analyzed. Results The number of previous anti-VEGF injections was 12.3 ± 15.0. During brolucizumab treatment, anatomical improvement was achieved and maintained in the height and width of the PEDs (p < 0.05). However, the visual outcome did not improve significantly (p > 0.05). A good response was achieved in 69.2% of eyes at 1 month and at the last visit. Relapse and complete resolution were observed in 27.8 and 23.1% of patients, respectively. The number of brolucizumab injections was 2.00 ± 0.85. Intraocular inflammation, vascular obstruction, and retinal pigment epithelial tears were not observed. Conclusion Intravitreal brolucizumab may be an effective and safe treatment option for refractory serous PEDs in patients with PCV.
Retinal sensitivity may vary by subtypes of cuticular drusen. This retrospective study included 52 eyes of 32 patients with cuticular drusen. All the patients underwent assessment of best-corrected visual acuity (BCVA), spectral-domain optical coherence tomography (SD-OCT), color fundus photography, fluorescein angiography, fundus autofluorescence, and microperimetry. The area occupied by drusen was counted using microperimetry. The cuticular drusen subtype was classified into 3 groups based on the SD-OCT findings. Age, BCVA, pattern standard deviation, area occupied by drusen, pupil size, and the false-positive rate were not significantly different (p > 0.05) according to the cuticular drusen type. The mean retinal sensitivity (MRS) (p = 0.063) and mean deviation (MD) (p = 0.098) showed marginally significant differences among the groups. In the subgroup analyses, type 1 and type 3 cuticular drusen showed significant differences in the MD (− 1.8 ± 2.1 vs − 5.1 ± 5.3; p = 0.011) and MRS (25.1 ± 2.2 vs 21.3 ± 5.7; p = 0.016) without differences in age, BCVA, or the area occupied by drusen (p > 0.05). The results indicate that depending on the subtypes of cuticular drusen type, the deterioration of retinal sensitivity is more likely to occur than decreased vision.
