“…The smooth corneal surface achieved with PTK can help patients obtain more vision improvements. A smooth corneal surface and less scar tissue on the cornea after PTK treatment showed that this approach might be a better and safer choice than lamellar keratoplasty [22]. However, the corneal topographic data were collected from the center or para-center of the cornea, a small and thin pterygium invading into the cornea within 2–3 mm could cause tremendous limbal changes but only mild central corneal parameter changes.…”

BackgroundRepeated surgery excisions could induce obvious irregular astigmatism in patients with recurrent pterygium. Our study is aimed to illustrate the effect of adjunct excimer laser phototherapeutic keratectomy (PTK) in limbal-conjunctival autograft transplantation on visual quality for patients with recurrent pterygium.MethodsRetrospective case-control study. Eyes that underwent pterygium excision with (PTK group) or without (control group) PTK from 2006 to 2017 were retrospectively included. Recurrence rate, preoperative and postoperative surface regularity index (SRI), surface asymmetry index (SAI), cylinder and LogMAR vision were collected. Postoperative anterior segment optical coherence topography and in vivo confocal microscopy were performed to monitor the cornea epithelium healing and cellular recovery process respectively.ResultsA total of 99 eyes of 99 patients were collected, of which 39 were treated with PTK and 60 without PTK. The mean follow-up time was 50.4 ± 38.1 months. The recurrence rate was 10.3% (4 eyes) in the PTK group and 13.3% (8 eyes) in the control group (p = 0.759). The SRI decreased 0.53 (range: − 0.88, 2.81), SAI decreased 0.53 (range: − 0.64, 2.94), and the cylinder decreased 2.08 (range:-0.16, 9.40) D in the PTK group, and the corresponding values were 0.48 (range:-0.45, 2.27), 0.27 (range:-1.06, 2.21) and 0.71 (range:-1.75, 3.55) D in the control group, respectively (Z = 1.76, 2.15, and 3.97, p = 0.005, 0.016, and 0.000 respectively). LogMAR vision improved in both groups after surgery, with an improvement of 0.18 (range: 0.00, 0.70) in the PTK group and 0.06 (range: − 0.12, 0.50) in the control group (Z = 4.08, p = 0.000). Besides, the eyes treated with PTK showed faster re-epithelization and better cellular recovery.ConclusionsFor recurrent pterygium, surgical excision with adjunct PTK might be a better option with improved corneal surface and vision outcomes.

“…When diplopia, severe astigmatism and visual disturbances were present a lamellar keratoplasty was performed (Barraquer, 1971). The results of the first study of 22 eyes was published separately (Dake et al, 1980): there was one recurrence and in all cases the motility and/or visual disorders improved.…”

The results of pterygium excision were assessed in an open study following a double-blind study on the effect of after-treatment with Strontium 90 (Sr 90). The results of the treatment of more complicated pterygia with disturbances of ocular motility and reduced visual acuity were also assessed; the treatment consisted of pterygium excision, conjunctival flaps or keratoplasty, and in the case of symblepharon fornix reconstruction. Thirty-three eyes with pterygia which had not previously been operated on, were treated with the "bare sclera" operative technique in combination with Sr 90 irradiation. After this treatment there were no recurrences. In the group of 18 recurrent pterygia which were treated with the same technique, two recurrences were seen. These results of irradiation are in sharp contrast with the 67% chance of recurrence when the "bare sclera" technique is used alone. The results of the more complicated pterygium operations were also successful. Visual acuity, motility and appearance improved markedly or became normal. Recurrences were rare (0-6%).
