“…This may be due to flap complications or laser correction (not properly centered on the eye or from irregular ablation) that may originate abnormal levels of higher-order aberrations (HOAs). 4,6,9,10 In a study by McCormick et al, 6 33 symptomatic post-LASIK eyes with irregular corneas experienced HOAs (mean6SD, 1.3860.58 mm) that were 2.3 to 3.5 times greater than those in an asymptomatic post-LASIK group and a normal preoperative eyes group (mean6SD, 0.5860.21 mm and 0.3860.14 mm, respectively, over a 6-mm pupil size and mean age of 44).Higher-order aberrations are measured with a wavefront aberrometer, providing quite useful information on the optical quality of the eye. This assesses the shape and severity of the deviated light rays when they pass through the optical system of the eye on the way to the retina.…”

“…10 Therefore, fitting rigid gas-permeable (RGP) contact lens or scleral contact lens (ScL) seems to be more effective than soft contact lens for irregular corneas. 4,[12][13][14] Scleral contact lens fitted after LASIK surgery is an adequate option to prescribe, especially when other contact lenses (including piggyback, hybrid, or RGP lenses) do not provide adequate VA or are not well tolerated (excessive movement and/or decentration). 15 A few studies [16][17][18][19][20] have included some cases about fitting ScL on irregular corneas after LASIK surgery.…”

“…However, despite recent advances in refractive surgery procedures, a small percentage of patients still have problems with their vision. [4][5][6][7] A recent study about LASIK Quality of Life published on the US Food and Drug Administration website 8 has shown that up to 4% of subjects were dissatisfied with their vision 3 months after LASIK surgery. In addition, this also caused a lot of difficulty with or even an inability to do normal activities in up to 1.0% of subjects not wearing correction.…”

“…These lenses permit increased oxygen to reach the cornea compared to PMMA contact lens by direct transmission through lens material. 5 Though soft contact lenses are used more commonly today, RGP lenses are still widely used for general refractive power correction 6 and for irregular and post-surgical corneas 7 when soft contact lens are not able to sufficiently improve visionquality.…”

Background: There have been significant advancements in contact lens designs and materials over the past few decades, the lenses still represent a foreign body in the ocular environment and may lead to physiological (corneal oedema or thinning) as well as mechanical (on corneal curvature) effects on the eye.As there are not many studies reporting the effect of contact lens on eyes in Indian population, this study was designed tofill the lacunae of knowledge in this context.Aims and Objective: To evaluate and compare the change in anterior central corneal curvature & central corneal thickness following use of soft contact lens (silicon-hydrogel) and Rigid Gas Permeable (fluoropolymer) contact lens.Materials and Methods: It was a Prospective, Observational, Comparative study Conducted at Venu Eye Institute & Research Centre, New Delhi. Forty eyes of 21 subjects who required contact lens were included in two groups: 20 eyes in group A (RGP contact lens users) and 20 eyes in group B (Soft contact lens users). A “baseline” parameters was measured prior to contact lens use & changes associated with contact lens wear was considered in relation to the normal baseline parameters when followed up at 3 and 6 months.Results: The Change in anterior central corneal curvature in both the groups was NOT statistically significant (p-value of >0.05) between pre-contact lens wear and with contact lens wear at 3 & 6 months. And, there was Significant Corneal thinning between pre-contact lens wear and with contact lens wear at 3 & 6 months in both the groups individually (p-value <0.05). However, on comparing the difference in change in CCT between both the groups was NOT statistically significant at 3 and 6 months.Conclusions: With contact lens use, there was no significant change in Anterior Central Corneal Curvature in Soft as well as RGP contact lens group at 3 & 6 months. Though there was significant central corneal thinning in both the groups individually at 3 & 6 months, However, on comparing the change in CCT between both the groups at 3 and 6 months was NOT significant.Asian Journal of Medical Sciences Vol.8(5) 2017 70-74

“…Contact lenses have been the mainstay management approach for post-LASIK ectasia and many options are available, such as hybrid, miniscleral, scleral, standard gas-permeable, and soft lenses. 6 The patient was a previous soft contact lens wearer before undergoing bilateral LASIK. She was prescribed gas-permeable lenses for both eyes at another provider after LASIK surgery and before the corneal transplant for her left eye.…”
