Background/Objectives: To analyse the higher-order aberrations (HOAs) and their visual impact on a paediatric blepharokeratoconjunctivitis (PBKC) cohort compared with healthy controls. Subjects/Methods: A prospective observational, case-control study of paediatric patients (≤ 16 years old) was designed. Subjects underwent a visual system wavefront aberrometry analysis to compare HOAs and their impact on visual quality. Results 150 eyes from 76 patients were included for analysis. The PBKC group consisted of 50 eyes, and the control group included 100 healthy eyes. Mean age was 10.39 ± 3.81 years for the PBKC group and 10.80 ± 3.61 years for the controls. Mean corrected-distance visual acuity (CDVA) was 0.24 ± 0.21 LogMAR in the PBKC group and 0.07 ± 0.1 in the controls (p = < 0.001). Mean astigmatism was 1.6 ± 1.98 in the PBKC group vs. 0.67 ± 0.76 in the controls (p = 0.01). Mean RMS of HOAs was 1.05 ± 1.7 in the PBKC group and 0.41 ± 0.18 in the controls (p = < 0.001). The mean modulation transfer function (MTF) in the PBKC group was significantly lower (16.37 ± 16.32) than in the controls (30.3 ± 23.57) (p = < 0.001). Corneal leucoma, neovascularization, phlyctenula, and pannus formation were associated with a greater risk of increased HOAs. Conclusions There was a significant increase in the total HOAs of PBKC eyes compared to healthy controls. The PBKC eyes aberrations profile, particularly coma, secondary astigmatism, quadrafoil, and pentafoil, had a significant visual impact. Leukoma, corneal neovascularization, pannus, and phlyctenula were strongly associated with increased HOAs.

IntroductionThe cataract is one of the main causes of visual alterations, which is normally treated with surgery since it improves the visual acuity of the patients, the object of the present investigation is to synthesize evidence on how the surgical intervention affects or changes the corneal aberrations.Methodologyconducted an exploratory review of the literature, observational studies on changes in corneal aberrations after cataract surgery with toric lens implant, using Pubmed, Google Scholar, Lilacs, Scopus, and Science Direct, searching and selecting articles from blindly and independently, following the PRISMA methodology.ResultsThe body of evidence selected was 4 articles published in a 6-year window, between 2011 and 2016. The average age of the surgically operated population was 65.3 ± 7.7 years, while the proportion according to sex there was a similar and greater change in corneal aberrations due to coma and trefoil.Conclusionssurgery with an incision equal to or less than 2.2 mm induces slight changes in the aberration of the total cornea, which increase before in eyes with a high pre-existence of corneal astigmatism and it is independent if the lens is toric or not.
