The effect of intraocular lens and lens eye on the treatment of macular splits in high myopia.

BACKGROUND

Macular retinoschisis in patients with high myopia is one of the main reasons for a decline in visual function and the perceived deformation of visual objects.

OBJECTIVE

This study aimed to investigate the therapeutic effect of cataract phacoemulsification and foldable intraocular lens implantation (FILI) combined with internal limiting membrane stripping (ILMS) in the treatment of macular retinoschisis in patients with high myopia.

METHODS

A total of 52 patients (55 eyes) who had been diagnosed with macular retinoschisis with high myopia between June 2019 and June 2020 were enrolled in the present study. Patients in the control group (25 eyes) received 23G vitreous surgery and macular ILMS and long-term inert gas (C3F8) filling of the vitreous cavity; patients in the research group (30 eyes) were additionally treated with cataract phacoemulsification and soft intraocular lens on the same treatment basis as the control group.

RESULTS

The difference in average BCVA between the control and the research groups was not statistically significant before the surgery (P> 0.05) but was statistically significant 12 months after the procedure (P< 0.05). The minimum foveal thickness was significantly decreased in the two groups after the surgery compared with before the procedure (P< 0.05).

CONCLUSION

Cataract phacoemulsification and FILI further improved the therapeutic effect of ILMS in the treatment of macular retinoschisis in patients with high myopia.
