Abstract

Abstract Introduction & Objectives : Uncorrected myopia is the leading cause of visual impairment globally. It can be corrected by refractive surgeries, such as Small Incision Lenticule Extraction (SMILE) and Femtosecond Laser- Assisted In Situ Keratomileusis (FS-LASIK). SMILE technique is less-invasive than FS-LASIK, characterized by all-in-one femtosecond laser and flapless procedure. Correction of low-moderate myopia requires a special concern because even slight decreased in visual quality may be noticed by the patients and affect their satisfaction. The purpose of this study to compare the refractive outcomes after SMILE and FS-LASIK in low-moderate myopia patients. Methods : This is a prospective analytical observational study that was conducted in a tertiary hospital in Indonesia. Four refractive outcome parameters (predictability, efficacy, safety, and stability) were assessed at 1 day, 1 week, and 1 month postoperatively. Results : SMILE was performed on 22 eyes with spherical equivalent (SE) -3.60±1.07 D and FS-LASIK on 20 eyes with SE -2.91±1.53 D. At 1 month, the predictability as the proportion of eyes within SE ±0.50 D were 95.5% in SMILE and 80% in FS-LASIK (p=0.174), the efficacy as the proportion of eyes achieving uncorrected distant visual acuity (UDVA) ≥20/20 were 63.6% in SMILE and 35% in FS- LASIK (p= 0.064), the stability as the proportion of eyes experiencing SE change >0.50 D were 4.5% in SMILE and 5% in FS-LASIK (p=1.000). No eyes from both groups had corrected distant visual acuity (CDVA) loss of ≥2 lines (p=1.000). Conclusion : SMILE and FS-LASIK were both predictable, effective, safe, and stable for low-moderate myopia patients.

Abstract

Abstract Introduction & Objectives : Types of Posterior capsule opacity (PCO) are membranous, fibrotic, or fibro-membranous. Surgical capsulotomy has been replaced by Neodymium-doped Ytrium Aluminim Garnet (Nd:YAG) as a PCO management nowdays. The initial energy use of the laser is influenced by variations in PCO density. Utilizing initial energy effectively can help to use less total laser energy. This study is to estimate energy Nd:YAG laser levels to treat various types of PCO. Methods : This is a observational descriptive study with cross-sectional design. This study retrieved initial and total capsulotomy Nd:YAG laser as a main variable on various types of PCO. The best corrected visual acuity (BCVA) before and after laser, size of hole capsulotomy, and complications of each type of PCO were evaluated. Results : A total 59 eyes of 49 patients with pseudophakia who underwent capsulotomy laser were included. The mean values of initial energy levels were 1,45±0,31 mJ for membranous PCO, 1,51±0,29 mJ for fibrous PCO, and 1,68±0,23 mJ for fibro-membran PCO. The mean summated energy levels for membranous PCO was 51,86±28,19 mJ, 78,86±44,81 mJ for fibrous PCO, 86,88±60,51 mJ for fibro- membran PCO. Complications were iritis, oculi hypertension, hyaloid rupture and IOL pitting were occurred in this study. Conclusion : Fibro-membran PCO required more initial and total laser energy compared to membranous and fibrous PCO

Abstract

Introduction: Two of the most popular refractive surgery methods currently used are Femtosecond Laser-Assisted In Situ Keratomileusis (FS-LASIK) which creates a flap using femtosecond laser and stromal ablation using excimer laser, and Small Incision Lenticule Extraction (SMILE), a flapless procedure in which a lenticule is extracted through a small incision. The aim of this study is to compare the visual acuity results of FS-LASIK and SMILE. Methods: This is a descriptive cross-sectional study. Data were collected from the medical record of patients who underwent FS-LASIK or SMILE procedure at Cicendo Eye Hospital, the national eye centre, in 2022. Patients were followed up at 1 day, 1 week, and 1 month postoperatively and visual acuity outcomes between the two procedures were compared. Results: A slightly higher percentage of eyes in FS-LASIK (46.6%) achieved a UCVA of 1.0 at 1 day postoperatively compared to SMILE (45.5%). At 1 week and 1 month, SMILE showed superior results with 83% and 94.6% of eyes achieving a UCVA of 1.0, meanwhile FS-LASIK had 72.2% and 86.2%. Residual refractive error at 1 month had a median of -0.6146 and -0.3125 in the FS-LASIK and SMILE groups. Conclusion: This study found better UCVA results in the FS-LASIK group compared to the SMILE group at 1 day postoperatively. Meanwhile, UCVA at 1 week and 1 month postoperatively, showed superior results in the SMILE group. Residual refractive error at 1 month postoperatively also showed better results in SMILE than FS-LASIK.
