Diffractive trifocal lens implantation with or without excimer laser enhancement: is a touch-up procedure a negative predictor for refractive and subjective outcome?

PURPOSE: To investigate the refractive results of a LASIK enhancement and its impact on treatment safety, efficacy, predictability and patient reported outcome in eyes after clear lens extraction and diffractive trifocal lens implantation. METHODS: A retrospective cohort multicentre study of Care Vision Refractive Centres in Germany compared two groups of patients. Group 1 consisted of eyes that had non-toric MIOL surgery only, whereas group 2 had a consecutive laser enhancement after 3 months follow-up. Refractive and subjective results of the two groups were compared. Patient reported outcome measurements were assessed by using a 30-item questionnaire with four subscales. (Spectacle Dependence, Eye Comfort, Freedom and Looking/Feeling Well). Refractive results were reported following standard reporting in refractive surgery. RESULTS: 139 eyes of 79 patients were included in which either MIOL surgery or MIOL surgery plus LASIK enhancement had been performed between January and December 2017. UDVA reached 0.1logMAR (0.8; 20/25) in 94% in group 2 and 85% in group 1. Compared to preoperative CDVA no change in Snellen lines of CDVA was shown in 89% in group 1 and in 93% in group 2. Spectacle dependence (P = 0.41), eye comfort (P = 0.15), freedom (P = 0.48) and looking/feeling well (P = 0.45) showed no statistically significant difference between both the groups. CONCLUSIONS: In patients with residual ametropia after MIOL implantation, LASIK provides a reliable, safe and efficient way to achieve the desired refractive outcome and patient satisfaction. We recommend performing Laser enhancement at 3 months after MIOL implantation (Bioptics) in trifocal MIOL patients that benefit from improvement of residual ametropia.

Perinatal complications and long-term neurodevelopmental outcome of infants with intrauterine growth restriction.

OBJECTIVE: The objective of the study was to evaluate perinatal and long-term complications of fetuses with intrauterine growth restriction (IUGR) compared with constitutionally small for gestational age (SGA) ones. STUDY DESIGN: The outcome of infants with IUGR and SGA born at the Medical University Graz (Austria) between 2003 and 2009 was retrospectively analyzed. Group assignment was based on birthweight, Doppler ultrasound, and placental morphology. The primary outcome was neurodevelopmental delay at 2 years corrected age. The secondary outcomes were perinatal complications. RESULTS: We included 219 IUGR and 299 SGA infants for perinatal and 146 and 215 for long-term analysis. Fetuses with IUGR were delivered earlier (35 vs 38 weeks) and had higher rates of mortality (8% vs 1%; odds ratio [OR], 8.3) as well as perinatal complications (24.4% vs 1.0%; OR, 31.6). The long-term outcome was affected by increased risk for neurodevelopmental impairment (24.7% vs 5.6%; OR, 5.5) and growth delay (21.2% vs 7.4%; OR, 3.4). CONCLUSION: IUGR infants are subject to an increased risk for adverse short- and long-term outcome compared with SGA children.
