The flap thickness outcomes with new dual femtosecond laser platform

Purpose: To evaluate flap thickness in femtosecond (FS) laser assisted LASIK operation for myopia performed with new LenSx dual platform using curved interface. Materials and methods: Fifty eyes of 26 patients (mean±SD age: 26.9±8.1 years, 53.8% were females) with myopia or myopic astigmatism operated with FS laser-assisted LASIK were evaluated in this study. Data on patient demographics, preoperative and postoperative keratometric and aberrometric parameters and flap thickness outcome including mean central flap thickness (MCFT), mean total flap thickness (MTFT), intra-FT range and flap thickness homogeneity (FTH) were recorded. Results: Flap thickness assessment revealed median values for MCFT to be 123 µm (range, 109 to 134), while MTFT was 123 µm (range, 109 to 133.7), Intra-FT range was 4.0 µm (ranged, 1 to 6) and FTH was -2 µm (range, -6 to 2). Overall flap thickness was thicker than planned by +3.0 μm (minimum, 109.0 μm with a −11.0 μm average difference and maximum, 133.7 μm with a +13.7 μm difference) with an average thickness standard deviation of 6.6 μm. Conclusions: In conclusion, our findings related to FS laser assisted LASIK surgery for myopia with new LenSx dual platform using curved interface revealed favorable corneal flap thickness outcome in terms of closeness of flap thickness to the intended value and low intra-flap range. Thus, our findings emphasize the likelihood of planning and producing more successful LASIK outcomes in terms of consistency and predictability of corneal flap thickness with use of new LenSx dual platform

Femtosaniye lazer yardımlı katarakt cerrahisinde ilk deneyimler

WOS: 000219242700004Objectives: To analyze the early experience and intraoperative complications of femtosecond laser-assisted cataract and refractive lens exchange (RLE) surgery. Materials and Methods: The initial 50 eyes of 29 patients who underwent cataract or RLE surgery between March 2013 and May 2013 were included in this study. All patients underwent anterior capsulotomy, lens fragmentation, and corneal incisions with the femtosecond laser (LenSx (R), Alcon Inc.). The operation was completed by phacoemulsification and implantation of an intraocular lens. Intraoperative complications were evaluated from patient charts and video reviews retrospectively. Results: The mean age of the patients included was 63.8 +/- 11.7 years. No suction break or anterior capsule tear occurred in any case. Small anterior capsular tags occurred in 11 eyes (22%). The capsulotomy buttons were free-floating in 7 eyes (14%), while capsulorrhexis was partially completed with microadhesions in 40 eyes (60%) and uncompleted in 3 eyes (6%). One eye (2%) had a posterior capsule rupture secondary to increase in the intracapsular pressure. Corneal incisions either were not preferred to be used in 8 eyes (16%) or could not be completed in 4 eyes (8%). Miosis occurred in 20 eyes (40%). No vision lost or dropped nuclei were observed. Conclusion: The use of femtosecond lasers in cataract and RLE surgery is safe. There had been no vision lost secondary to complications.Amaç: Femtosaniye laser yardımlı katarakt ve refraktif lens değişimi (RLD) cerrahisinde intraoperatif komplikasyonlar ve ilk deneyimlerin değerlendirilmesi. Gereç ve Yöntem: 2013 Mart-2013 Mayıs tarihleri arasında femtosaniye laser yardımlı katarakt ve RLD ameliyatı yapılan 29 hastanın 50 gözü çalışmaya alındı. Tüm hastalara Femtosaniye laser cihazı (LenSx®, Alcon Inc.) ile komple prosedür (kapsülotomi, lens fragmantasyonu ve korneal kesiler) uygulandı. Ameliyatlar fakoemülsifikasyon ve göz içi lensi yerleştirilerek tamamlandı. İntraoperatif komplikasyonlar retrospektif olarak hasta dosyalarından ve ameliyat videolarından değerlendirildi. Bulgular: Hastaların yaş ortalaması 63,8±11,7 (SD) yıl idi. Vakum kaybı ya da anterior kapsül yırtığı hiçbir gözde oluşmadı. On bir gözde (%22) küçük ön kapsül etiketleri oldu. Yedi gözde (%14) serbest kapsülotomi, 40 gözde (%60) mikroadezyonlarla birlikte parsiyel tamamlanmış kapsüloreksis ve 3 gözde (%6) inkomplet kapsüloreksis izlendi. Bir gözde (%2) intrakapsüler basınç artışına bağlı arka kapsül rüptürü gelişti. Korneal kesiler 8 gözde (%16) kullanılmak istenmedi, 4 gözde (%8) tamamlanamadı. Miyozis 20 gözde (%40) meydana geldi. Vizyon kaybı ya da nükleus drop gözlenmedi. Sonuç: Femtosaniye laserlerin katarakt ve RLD cerrahisinde kullanımı güvenlidir. Komplikasyonlara bağlı görme kaybı gelişmemiştir

Subjective and objective clinical outcomes of a new trifocal toric intraocular lens and effect of femtosecond laser cataract surgery

Purpose: To evaluate the clinical outcomes and quality of life following implantation of PanOptix toric intraocular lens (IOL) and to compare the outcomes following femtosecond laser assisted cataract surgery (FLACS) and standard cataract surgery (SCS). Methods: This comparative retrospective study included 79 eyes of 55 patients underwent cataract or refractive lens exchange surgery between April 2017 and January 2020 in Bayindir Hospital and Kaskaloglu Eye Hospital. Corneal (CA) and refractive astigmatism (RA), uncorrected visual acuities for distant, intermediate, and near (UDVA, UIVA, and UNVA), low contrast distance visual acuity, rotational stability, defocus curves, photopic and mesopic contrast sensitivity (CS), visual function-14 (VF-14) test, presence of dysphotopsia, and need for spectacles were evaluated at postoperative third month. Outcomes were compared between FLACS and SCS group. Results: The mean UDVA, UIVA, and UNVA were 0.05 +/- 0.07, 0.08 +/- 0.08, and 0.06 +/- 0.07 logMAR, respectively. All patients achieved > 0.3 logMAR uncorrected visual acuity for all distances. UDVA was found significantly better in FLACS group (p = 0.03). All eyes had <= 1 D of subjective postoperative RA. Defocus curve had two peaks at 0 and -1.50 D. Spectacle independence was achieved in 88.7% of patients. Photopic and mesopic CS was within normal range in all patients. The mean VF-14 score was 98 +/- 2. The mean IOL axis rotation was 2.1 degrees +/- 2.3 degrees. Only one patient reported seeing disturbing halos. Conclusions: This trifocal toric IOL effectively reduced refractive astigmatism and provided excellent visual outcomes with high spectacle independence, patients' satisfaction, and good rotational stability. FLACS might have an impact on optimal postoperative results

Patients satisfaction and clinical outcomes of binocular implantation of a new trifocal intraocular lens

Purpose To evaluate the clinical outcomes following bilateral implantation of PanOptix intraocular lens (IOL). Methods This study included consecutive patients scheduled to undergo cataract or refractive lens exchange surgery between October 2017 and June 2018 at two centers. Manifest refraction, uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA, 60 cm) and uncorrected near visual acuity (UNVA, 40 cm), defocus curves, presence of dysphotopsia, need for spectacles, presence of posterior capsule opacification and visual function were evaluated at 6 months after surgery. Results The IOL was implanted in 138 eyes of 69 patients. The mean binocular UDVA was 0.02 +/- 0.05 logMAR, UIVA 0.06 +/- 0.07 logMAR and UNVA 0.05 +/- 0.07 logMAR. Defocus curve showed two peaks at 0.00 D and - 1.50 D. Complete spectacle independence was reported in 94.2% of the patients. The mean VF-14 test result was 97.7 +/- 2.2 (93.2-100). Only one patient (1.4%) reported seeing bothersome halos. The presence of posterior capsule opacification was noted in seven eyes (10%), whereas Nd:Yag capsulotomy was required only in one eye. Conclusions This trifocal IOL provided excellent visual outcomes at all distances with high spectacle independence and patient's satisfaction

Femtosecond laser–assisted cataract surgeries reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery:Baseline characteristics, surgical procedure, and outcomes

PurposeTo describe a large cohort of femtosecond laser–assisted cataract surgeries in terms of baseline characteristics and the related outcomes.SettingEighteen cataract surgery clinics in 9 European countries and Australia.DesignProspective multicenter case series.MethodsData on consecutive eyes having femtosecond laser–assisted cataract surgery in the participating clinics were entered in the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). A trained registry manager in each clinic was responsible for valid reporting to the EUREQUO. Demographics, preoperative corrected distance visual acuity (CDVA), risk factors, type of surgery, type of intraocular lens, visual outcomes, refractive outcomes, and complications were reported.ResultsComplete data were available for 3379 cases. The mean age was 64.4 years ± 10.9 (SD) and 57.8% (95% confidence interval [CI], 56.1-59.5) of the patients were women. A surgical complication was reported in 2.9% of all cases (95% CI, 2.4-3.5). The mean postoperative CDVA was 0.04 ± 0.15. logarithm of the minimum angle of resolution. A biometry prediction error (spherical equivalent) was within ±0.5 diopter in 71.8% (95% CI, 70.3-73.3) of all surgeries. Postoperative complications were reported in 3.3% (95% CI, 2.7-4.0). Patients with good preoperative CDVA had the best visual and refractive outcomes; patients with poor preoperative visual acuity had poorer outcomes.ConclusionsThe visual and refractive outcomes of femtosecond laser–assisted cataract surgery were favorable compared with manual phacoemulsification. The outcomes were highly influenced by the preoperative visual acuity, but all preoperative CDVA groups had acceptable outcomes
