“…[5] The key features considered to select the optimum BCL include its oxygen permeability, water content, wetting agents, diameter, base curve and modulus. [6] Several studies have investigated the effect of different materials on the epithelial healing, visual outcomes and subjective assessment of pain and discomfort after corneal refractive surgery; [7][8][9][10][11] however, they could not determine which specific parameters influence the contact lens's performance or its role during the healing process. PureVision and PureVision2 silicone hydrogel (SiH) contact lenses are made of the Balafilcon A that contains 36% water and AerGel™ technology lens material that are manufactured by cast molding process.…”

To compare the efficiency and safety of two bandage contact lenses after photorefractive keratectomy (PRK). Methods: In this double-blind study, 45 patients (90 eyes) received PRK in both eyes and wore bandage contact lenses (BCLs), PureVision (Bausch & Lomb, Rochester, NY, USA) in one eye and PureVision2 (Bausch & Lomb, Rochester, NY, USA) in the other eye, randomly assigned. The medication regimen after surgery was the same for both eyes. The epithelial defect's size, conjunctival hyperemia and lens centration were graded objectively using slit-lamp biomicroscopy on days 1, 3 and 5 after surgery. Also ocular symptoms of discomfort including tearing, photophobia, foreign body sensation and visual fluctuations were assessed subjectively at each visit. Results: The mean epithelial defect size on the first day after operation was similar in eyes fitted with PureVision (30.08 ± 5.30 mm²) and PureVision2 (30.25 ± 5.72 mm 2) lenses. (p=0.79) Contact lens deposits and bulbar hyperaemia on days 1 and 3 after PRK were similar between the two eyes, but were significantly greater on day 5 for PureVision2 lenses. (p= 0.02; p= 0.04 respectively) There was no difference in contact lens decentration, and discomfort symptoms including pain, tearing, foreign body sensation, photophobia and visual fluctuations between the eyes fitted with PureVision and PureVision2. (p>0.05) Conclusions: PureVision and PureVision2 contact lenses are equivalent as bandage lenses in the important aspects corneal re-epithelialization and subjective comfort., although PureVision2 led to a higher incidence of contact lens deposits and conjunctival hyperemia early post-PRK.

“…Bandage contact lenses (BCLs) are often used to promote corneal wound healing and reduce patient discomfort after laser refractive surgery [ 4 – 6 ], particularly following procedures such as photorefractive keratectomy (PRK) and laser epithelial keratomileusis (LASEK). As there are many different types of contact lens materials and designs available on the market, researchers have been investigating the most suitable type of contact lens to be used after laser refractive surgery [ 7 – 9 ]. Conventional hydrogel BCLs had low oxygen transmissibility, which might potentially cause hypoxic complications of the cornea when prescribed using a continuous wear modality [ 6 , 10 ].…”

Purpose. To examine the immediate use of bandage contact lenses (BCLs) for improving patient comfort after small incision lenticule extraction (SMILE) surgery. Methods. This is a prospective randomized controlled study in which one hundred and seventy-eight patients undergoing SMILE were randomly allocated to three groups: group A wore BCLs for 8 hours postsurgery, group B wore BCLs for 24 hours postsurgery, and group C did not wear any BCLs postsurgery. Eight subjective symptoms including photophobia, tearing, pain, foreign body sensation, burning, blurred vision, sting, and dry eyes were prospectively evaluated at 2 hours, 4 hours, 8 hours, and 24 hours, using a questionnaire with a total score of 24. The scores of symptoms and signs were compared between the three groups. Results. There was a statistically significant time effect on scoring, which implicated a decline in symptoms over time after surgery (P<0.001). There was also a significant interaction between time and the treatment group (P<0.01). The total symptom score of groups A and B (5.85 ± 3.97 and 5.99 ± 4.67, respectively) was significantly lower than that of group C at 2 hours postsurgery (7.35 ± 4.86, P<0.05), especially in tearing and pain (P<0.05). The level of corneal oedema at 24 hours postsurgery was also statistically significantly different between the three groups (P<0.001), and the post hoc test showed that groups A and B were lower than group C (P<0.01). Conclusion. Silicon hydrogel BCLs applied immediately after SMILE surgery can relieve postsurgical symptoms of tearing and pain, improving overall patient comfort, and reduce corneal oedema. This trial is registered with ChiCTR-ONRC-13003114. Precis. The application of silicone hydrogel bandage contact lenses immediately after SMILE surgery has the potential to improve patient comfort, corneal healing, and patient satisfaction following SMILE.

“…Numerous studies have evaluated the clinical performance of different SiH contact lens materials for bandage use after PRK or LASIK/LASEK. [6][7][8][9]14,[19][20][21][22] However, there are relatively limited studies comparing the effectiveness of bandage contact lenses after CXL. Kocluk et al 23 reported that there were similar symptoms and clinical findings with the use of Balafilcon A and Hioxifilcon A lenses after CXL.…”

“…Another study showed that faster and smoother reepithelialisation occurred with an Asmofilcon A lens compared to a Lotrafilcon B lens. 8 Moreover, in two comparative studies of Lotrafilcon B and Comfilcon A after PRK, Eliacik et al 21 reported that Comfilcon A had better results in discomfort score and re-epithelialisation time. However, Mohammadpour et al 22 identified that there were similar results in pain and discomfort with both lenses.…”

Silicone-hydrogel (SiH) contact lenses are frequently used as a bandage after anterior segment surgical procedures. Several types of lenses may exhibit clinical performances with different characteristics. This study aims to evaluate the efficacy of two SiH contact lenses following corneal crosslinking (CXL). Forty-nine keratoconus patients scheduled for consecutive CXL surgery in both eyes were included in this comparative, double-blind, prospective study. A Balafilcon A
