Raindrop inlay plus LASIK

A hydrogel corneal inlay (Raindrop, Near Vision) with concurrent LASIK is safe and effective for treating myopic presbyopia, suggest the results of a prospective non-randomised clinical trial. Thirty eyes received the implant with concurrent LASIK. The inlay was implanted in the non-dominant eye under a flap created using a femtosecond laser. At each postoperative visit, the mean CDVA and CNVA were within one half line of preoperative measurements and no eye lost two or more lines of CDVA. The mean binocular UDVA, UIVA and UNVA were better than 20/25 Snellen at all postoperative visits. By six months, 93 per cent of patients had a binocular Snellen acuity of 20/25 or better across all visual ranges.

Demographics of cataract surgery
after LASIK

Researchers evaluated 40 eyes of consecutive patients scheduled for cataract surgery after previous LASIK. One control group included 606 eyes of matched axial lengths. A second control group included 3,642 eyes scheduled for cataract surgery. Patients in the study group were significantly younger. They were also more likely to be male, and had higher rates of higher order aberrations.

Keratitis after SMILE?

Diffuse lamellar keratitis (DLK) is a potential complication after small-incision lenticule extraction, although it had a low incidence, Chinese researchers report. The study enrolled 1,112 eyes of 590 patients. Eighteen eyes (1.6 per cent) developed DLK. These patients presented one to three days postoperatively with mild to moderate inflammation. Thirteen eyes (72.2 per cent) had Stage 1 DLK, four (22.2 per cent) had Stage 2, and one (5.6 per cent) had Stage 3. After intensive treatment with topical corticosteroids, the Stage 1 and Stage 2 cases resolved within three weeks and the Stage 3 case resolved in one month. The postoperative CDVA was the same or better than preoperatively in all eyes. There was a statistically significant increase in the incidence of DLK with thinner lenticules and larger diameter lenticules.
