ABSTRACT
Objective:To observe the changes in refractive status of eyes with idiopathic macular hole (IMH) after vitrectomy and phacoemulsification and IOL implantation (combined surgery).Methods:A retrospective clinical study. From January 2016 to June 2019, 51patients (56 eyes) of IMH who underwent combined surgery at the Tianjin Medical University Eye Hospital. were included in the study. Among them, there were 17 males and 34 females with the average age of 66.79±4.33 years. All the affected eyes underwent BCVA, retinoscopy and axial length (AL) measurement. The IOL power was calculated according to the SRK-T formula and the refractive power (predicted value) was predicted. The average BCVA of the affected eye was 0.20±0.13. The average anterior chamber depth was 2.89±0.28 mm. The average △corneal astigmatism was 0.73±0.43 D, the average AL was 22.92±0.70 mm, the average predicted refractive power was 0.10±0.66 D. All the affected eyes underwent standard transciliary flat part three-channel 25G combined surgery. Six months after the operation, the actual value (actual value) of the diopter after the operation was measured with the same equipment and method before the operation. Paired t test was used to compare the difference between the predicted value and the actual value. Results:Six months after the operation, the actual value of the refractive power was -0.19±0.64 D. Compared with the pre-operative refractive power, the difference was not statistically significant ( t=1.665, P=0.102). The difference between the actual value and the predicted value was -0.33± 0.81 D. Conclusions:The refractive status of the IMH eye undergoes myopia drift after combined surgery. The preoperative IOL power budget can be appropriately reserved for +0.3 D hyperopia.
